Quality Control

Our n-(Acetylglycyl)-3-Aminopropyltrimethoxysilane solution is produced under a strict quality management system. Each batch is analyzed to ensure consistent concentration, purity, and performance. Certificates of Analysis (COA) detailing assay, solvent content, and identification are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, keep the container tightly sealed when not in use and away from heat and open flames. The methanol solvent is flammable; observe all relevant safety regulations for flammable liquids.
