Quality Control

Our 5,7-Eicosadiyn-1-Ol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high chemical purity and consistency. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles, supporting compliance with research and cGMP-grade requirements where applicable. Specifications are designed to meet the exacting standards of advanced synthetic applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label or COA. Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed in a cool, dry place after opening to minimize exposure to moisture and air. Keep away from incompatible materials such as strong oxidizing agents.
