Quality Control

Our Propionyl-Ile-Ile-Gly-Leu-Nh2 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and chiral analysis to ensure sequence integrity. We provide full traceability and a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with customer specifications and industry best practices for research-grade peptides.

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 minimize moisture absorption. For extended storage under inert atmosphere, contact our technical team for specific recommendations.
