Quality Control

Our peptide building blocks undergo rigorous quality testing to ensure compliance with industry standards for pharmaceutical intermediates. Each batch is characterized by advanced analytical techniques including HPLC, MS, and NMR to confirm identity, purity, and correct stereochemistry. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive); ensure the container is sealed under inert atmosphere or with desiccant after each use to maintain stability and purity. Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
