Certificate of Analysis Library

Certificate of Analysis Library

⚠️ Research Use Only — All compounds documented in this library are supplied exclusively for in vitro and preclinical laboratory research. Not for human or veterinary use.

Every batch of research peptide supplied by CrewChems undergoes independent third-party testing before release. Below you will find the complete archive of Certificates of Analysis (COAs), searchable by batch ID, compound name, or test date. Each COA includes HPLC purity data, LC-MS identity confirmation, and endotoxin test results.

How to Use This Library

  1. Search by Batch ID, Compound Name, or Test Date using the search bar below.
  2. Locate your batch entry in the results table.
  3. Click Download COA to retrieve the PDF Certificate of Analysis for that batch.
  4. Contact us at support@crewchems.com if your batch ID is not found.

  • Batch ID: Unique identifier for each manufactured lot.
  • Compound Name: Full IUPAC or common research name of the peptide.
  • Manufacture Date: Date the batch was synthesized and lyophilized.
  • Test Date: Date independent third-party testing was completed.
  • Third-Party Lab: Name of the accredited testing laboratory.

Testing Standards

  • HPLC Purity: ≥99% purity threshold — batches below this standard are rejected.
  • LC-MS Identity: Molecular identity confirmed by liquid chromatography-mass spectrometry.
  • Endotoxin Testing: LAL (Limulus Amebocyte Lysate) method per USP standards.
