Certificates of Analysis
Certificates of Analysis
Independent Laboratory Verification · Every Batch
Third-party laboratory test reports for all research compounds. Every batch of every product undergoes independent analytical verification before release — providing researchers with the documentation they need to proceed with confidence.
What is a Certificate of Analysis?
A Certificate of Analysis (CoA) is a quality assurance document issued by an independent, accredited analytical laboratory confirming that a specific batch of compound meets its defined specification.
Unlike self-reported purity claims, a third-party CoA provides independently verified analytical data — including chromatographic purity results, mass spectrometry identity confirmation, and testing for common contaminants — giving researchers the evidence base required for credible scientific work.
CoAs are available for every product and every batch. Researchers may request the CoA for their specific batch by contacting us with their order details.
What Our CoAs Verify
Each Certificate of Analysis covers six analytical parameters assessed by accredited independent laboratories.
HPLC Purity
High-performance liquid chromatography quantifies the percentage of the compound of interest in the sample, identifying any related impurities, degradation products, or synthetic by-products.
Mass Spectrometry Identity
Electrospray ionisation mass spectrometry (ESI-MS) confirms the molecular weight of the compound matches its theoretical monoisotopic mass, providing definitive identity confirmation.
Endotoxin Testing
Limulus amebocyte lysate (LAL) assay measures bacterial endotoxin levels. Low endotoxin is critical for cell culture studies where endotoxin contamination would confound experimental results.
Microbial Limits
Testing for total aerobic microbial count (TAMC), total yeast and mould count (TYMC), and specific pathogens ensures compounds are microbiologically suitable for research applications.
Residual Solvents
Gas chromatography (GC) analysis tests for residual synthesis solvents including acetonitrile, DMF, DMSO, and TFA — ensuring compounds are free from potentially cytotoxic solvent residues.
Visual & Physical Inspection
Visual appearance assessment, solubility testing, and physical characterisation including moisture content where relevant. Ensures the product matches expected physical description for its form.
How to Read Your Certificate of Analysis
Confirm the Batch Number
Match the batch number on your CoA to the label on your product vial. Each batch is uniquely numbered and the CoA is specific to that batch only
Verify Identity
Check that the compound name, sequence, and molecular weight in the MS data match the theoretical values for your compound
Review Purity
The HPLC chromatogram shows peak area percentage — the main peak represents your compound. Values ≥98% indicate high-purity research-grade material
Check the Laboratory
Confirm the issuing laboratory is independent from the manufacturer and holds relevant analytical accreditation (ISO 17025 or equivalent)
Frequently Asked Questions
How do I request a CoA for my order?
Contact us with your order number and the product you require the CoA for. We will provide the CoA for your specific batch, matching the batch number on your product label.
Are CoAs issued by independent laboratories?
Yes. All CoAs are issued by accredited third-party analytical laboratories independent of the manufacturing facility. This ensures test data is unbiased and scientifically credible.
What purity standard do your products meet?
All products are released to a minimum HPLC purity of ≥98.0%. Many compounds achieve ≥99% purity. The specific result for each batch is documented in the CoA.
Is a CoA included with every order?
CoAs are available on request for all products. Contact our team with your order details and we will provide the certificate promptly. CoAs can also be used for institutional compliance purposes.
What testing methods are used?
Standard analytical methods include reverse-phase HPLC (RP-HPLC) for purity, electrospray ionisation mass spectrometry (ESI-MS) for identity, LAL assay for endotoxin, and GC for residual solvents.
Can I use a CoA for institutional compliance?
Yes. CoAs are frequently used by researchers to document compound quality for institutional review boards, grant reporting, and publication methodologies. Contact us if specific documentation formats are required.
Research Use Only — Analytical Documentation
Certificates of Analysis confirm analytical parameters for research-grade compounds intended solely for qualified laboratory research applications. CoA data does not constitute approval or endorsement for any therapeutic, clinical, or human consumption use. All research must be conducted in compliance with applicable institutional and regulatory requirements.
