Quality Control

Our production of n-(n-Acetylleucyl)-3-Aminopropyltriethoxysilane adheres to a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and FTIR for structural confirmation, and Karl Fischer titration for moisture content. Certificates of Analysis (COA) documenting all specifications are provided to ensure traceability and compliance with your material requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
