Quality Control

Our Cholesteryl n-(15,16-Dihydroxy-4,7,10,13-Tetraoxa-Hexa-Decyl)Carbamate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and specific tests for residual solvents and moisture content. Certificates of Analysis (COA) documenting full compliance with agreed specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as specified on the label or COA. Due to its hygroscopic nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
