Quality Control

Our H-Ser-Phe-Leu-Leu-Arg-Asn-Nh2 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, MS for identity confirmation, and chiral analysis to ensure sequence integrity. A comprehensive Certificate of Analysis (COA) detailing purity, related substances, residual solvents, and other critical parameters is provided with every shipment to guarantee traceability and compliance with your research or development specifications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This material is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to prevent condensation. For extended storage, consider under an inert atmosphere.
