Quality Control

Our peptide products are manufactured under strict quality management systems. Each batch of β-Mercapto-Beta,β-Cyclopentamethylene-Propionyl-D-Ile-Phe-Ile-Asn-Cys-Pro-Arg-Gly-Nh2 undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and chiral analysis. Certificates of Analysis (COA) detailing all specifications are provided and available upon request to ensure full traceability and compliance with your research or cGMP guidelines.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., argon or nitrogen) at a controlled temperature of -20°C or below for long-term stability. Allow the sealed vial to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake.
