Certificate of Analysis (COA)
Batch-specific documentation, published as certificates clear testing
Our testing standards
What a COA confirms
- Compound identity confirmed by mass spectrometry (MS-UPLC)
- Purity percentage established by HPLC area integration
- Unique batch/lot number traceable from synthesis to vial label
- Date of manufacture and assigned expiry date
- Recommended storage conditions specific to the compound
- Molecular formula, molecular weight, and empirical formula
- Issuing laboratory name, accreditation number, and analyst signature
Reading Our Certificates of Analysis
Labelled quantity is net peptide content, not gross salt weight. Vials are deliberately overfilled during aliquoting to ensure the stated peptide content is met after production losses, which is why measured net content on a certificate is typically above the labelled amount.
Request a Certificate of Analysis
Submit your compound name and batch number below. COA documents are sent to your registered email address within one business day. Include your order number to match a specific lot.
COA documents are issued by our independent third-party testing laboratory and are available to view and download directly from each product page, or by searching our COA database using your order number or batch lot number.

Safety Data Sheets (SDS/MSDS)
A Safety Data Sheet is maintained for every compound in our catalog. It covers hazard identification, handling procedures, storage conditions, PPE requirements, and disposal. SDS documents comply with the OSHA Hazard Communication Standard, 29 CFR 1910.1200 (HCS 2024, aligned to GHS Rev. 7 with elements of Rev. 8), and can be downloaded directly from the library above or from any product page.
MSDS Document Contents
- Product identification, trade name, and CAS registry number
- Hazard identification and classification under the OSHA Hazard Communication Standard, 29 CFR 1910.1200 (HCS 2024, aligned to GHS Rev. 7 with elements of Rev. 8)
- Composition, ingredient breakdown, and impurity profile
- First aid procedures for exposure routes (inhalation, skin, eye, ingestion)
- Fire-fighting measures and suitable extinguishing media
- Accidental release and spill containment procedures
- Safe handling conditions and incompatible materials
- Recommended storage temperature, humidity range, and container type
- Exposure limits (where established) and required PPE specifications
- Physical and chemical properties including solubility and stability data
- Toxicological data and reproductive hazard classification where applicable
- Disposal considerations in accordance with federal and local EPA regulations
Laboratory handling guidelines
- Handle exclusively in a properly equipped laboratory with adequate ventilation and appropriate biosafety rating
- Wear full PPE at all times: lab coat, nitrile gloves, and ANSI-rated eye protection as a minimum
- Reconstitute lyophilized peptides using a laboratory-appropriate diluent such as sterile PBS, assay buffer, DMSO, or dilute acetic acid as specified by your research protocol. For in-vitro research use exclusively.
- Store lyophilized peptides at 2-8 degrees Celsius short term or at -20 degrees Celsius for extended storage, as specified on the COA
- Maintain complete chain of custody records, research logs, and handling documentation throughout all experimental phases
- Not for human, veterinary, or food-contact use under any circumstances. Dispose of according to your institutional and EPA-compliant waste procedures.
Every sheet is downloadable above and on the matching product page. Contact our team if you need one that is not listed.
Third-Party Testing
Independent HPLC and mass spectrometry verification
Every batch of compound we supply is submitted to an independent, accredited third-party laboratory for HPLC purity analysis and mass spectrometry identity confirmation.
We do not conduct in-house testing. Removing the conflict of interest from the analytical process is the most important quality decision we make.
Results are reviewed by our team before any batch is released for dispatch. Batches that do not meet our minimum >99% purity threshold are rejected.
