Custom Reference Standards — Purified, Characterized, and Ready to Use
When a certified standard doesn't exist, HIPSOUL prepares it. We isolate and purify your impurity, degradant, natural product, or active ingredient, confirm its purity and structure, and deliver it with COA-ready documentation — milligram to multi-gram scale.
Reference Standards We Prepare for You
If you can define the target, we can prepare it as a characterized reference material — at the purity and quantity your project demands.
Custom Reference Standards
Bespoke primary and secondary reference standards prepared to your specification when no commercial or pharmacopoeial standard is available.
Impurity Reference Standards
Isolated and purified individual impurities prepared as reference materials for related-substances methods, system suitability, and specification setting.
Degradation Product Standards
Degradants generated through controlled degradation, then isolated and characterized for use as markers in stability-indicating methods.
Natural Product Reference Compounds
Single high-purity compounds isolated from botanical extracts and complex matrices, prepared as reference materials for identity and potency work.
Active Ingredient Reference Materials
Purified APIs and active compounds prepared and characterized as working or primary standards for assay and QC.
Small-Batch Purified Compounds
Defined quantities of purified compound delivered for research, method development, or characterization — with documentation to match.
When a Custom Reference Standard Becomes Essential
These are the situations where teams come to HIPSOUL — when the standard you need simply isn't on a catalogue.
No Commercial Standard Exists
Your impurity, degradant, or novel compound has no certified source — so it has to be prepared, characterized, and documented from scratch.
Your Method Needs a Marker
Developing or validating a related-substances method requires a pure, identified impurity standard to establish specificity and system suitability.
A Regulator Wants It Qualified
Identifying and qualifying an impurity for submission often requires an isolated, characterized reference material to support the response.
Stability Reveals New Degradants
Degradants emerging on stability must be characterized and, often, prepared as standards to track them through your shelf-life program.
QC Needs a Working Standard
Routine release and testing need a consistent, documented working standard — prepared and re-supplied to the same specification.
Research Needs a Pure, Known Compound
Bioactivity, characterization, or comparative studies require a single pure compound of confirmed identity and purity.
Preparation Capability — Purity, Identity, and Documentation
A reference standard is only as good as its characterization. We prepare materials that are pure enough, identified with confidence, and documented well enough to use the day they arrive.
Isolation & Purification
Preparative HPLC, flash, chiral, and orthogonal techniques isolate your target from crude mixtures, extracts, or degradation samples to the required purity.
Purity Verification
Achieved purity is verified by HPLC (and orthogonal methods where needed), with the result documented to support the standard's intended use.
Structure Confirmation Support
Identity is confirmed by MS and, where required, NMR — so your standard's structure is established, not assumed.
COA-Ready Documentation
Each standard ships with a documentation pack — purity, identity, quantity, and method references — formatted to drop into your records or submission.
Reproducible Re-Supply
Once a standard is established, we re-prepare to the same specification so your QC and methods stay consistent over time.
Difficult & Closely-Related Targets
Isomers, structurally-similar impurities, and trace targets — the standards hardest to source are where we add the most value.
From Target Definition to a Documented Standard in Hand
A clear, outcome-driven path. Every project ends with a characterized reference standard and a documentation pack you can use immediately.
Define the Standard & Spec
We agree the target compound, required purity, quantity, intended use, and characterization needs. NDA signed before any disclosure.
Source or Generate the Target
The target is sourced from your sample, isolated from a mixture, or generated (e.g. via controlled degradation) ready for purification.
Isolate & Purify
Preparative techniques isolate the target to the required purity, with fractions collected and tracked.
Verify Purity & Confirm Structure
Purity is verified (HPLC/orthogonal) and identity confirmed (MS/NMR as required) against your specification.
Document & Deliver
The standard is dried, weighed, vialed, and shipped with a COA-ready documentation pack confirming purity, identity, and quantity.

What Our Reference Standards Enable
A characterized standard is a tool. Here's what clients do with the reference materials we deliver.
Reference Standards We've Delivered
Real projects where HIPSOUL delivered the characterized standard a client needed — at the purity, scale, and documentation level they specified.
Pharmaceutical
Impurity Standard Prepared at >99% for a Related-Substances Method
A pharma client needed an impurity reference standard that didn't exist commercially. HIPSOUL isolated and purified it to >99%, confirmed structure by MS and NMR, and delivered it with COA-ready documentation for method validation.
Stability
Degradant Isolated and Documented as a Stability Marker
A degradant appearing on stability needed to be tracked. HIPSOUL generated, isolated, and characterized it as a reference standard, enabling the client's stability-indicating method to monitor it reliably.
Natural Products
Botanical Reference Compound Prepared and Re-Supplied to Spec
A nutraceutical client needed a single bioactive reference compound, then ongoing supply. HIPSOUL isolated it to high purity, characterized it, and re-prepared subsequent batches to the same specification.

Frequently Asked Questions
Answers to the questions quality, regulatory, and research teams ask most before commissioning a custom reference standard.
What is a custom reference standard, and when do I need one?
A custom reference standard is a purified, characterized compound prepared specifically for your use when no commercial or pharmacopoeial standard exists — for example an unusual impurity, a degradant, or a novel compound. You need one when method development, impurity qualification, QC, or a regulatory query requires a known, documented material.
What documentation comes with each standard?
Each standard ships with a COA-ready documentation pack stating purity, identity, quantity, and method references. Purity is determined by HPLC; identity is confirmed by MS and, where required, NMR.
What purity grades can you prepare?
We routinely prepare research grade (≥95%), method-ready (≥98%), and reference grade (≥99%) materials, and take on difficult targets such as isomers and closely-related impurities. You specify the grade your application needs.
Can you prepare an impurity or degradation product standard?
Yes. We isolate and purify individual impurities, and generate, isolate, and characterize degradation products, preparing them as documented reference standards for use as markers in your methods.
Can you prepare natural product reference compounds?
Yes. We isolate single high-purity compounds from botanical extracts and complex matrices and prepare them as characterized reference materials for identity and potency work.
Can you re-supply the same standard later?
Yes. Once a standard is established, we re-prepare it to the same specification, so your QC and methods remain consistent over time.
What quantities can you deliver?
From milligrams (typical for impurity and degradant standards) to multi-gram quantities for ongoing QC, all delivered to the same documented purity.
How do you confirm the structure of a prepared standard?
Identity is confirmed by mass spectrometry and, where required, NMR, with high-resolution accurate-mass available for molecular formula confirmation — so the structure is established, not assumed.
Do you sign NDAs and protect proprietary compounds?
Yes. We sign mutual NDAs before any technical discussion. Novel compounds, proprietary structures, and unpublished data are held in strict confidence and never disclosed to third parties.
Do you accept international projects and samples?
Yes. We work with clients across the USA, Europe, India, Australia, and the Middle East, and advise on import/export documentation for regulated materials.
