Quality Control

Our production of 2,2-Bis(3-Triethoxysilylpropoxymethyl)Butanol: 50% In Ethanol adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay, solvent content, and identity confirmation, to ensure consistency and performance. Certificates of Analysis (COA) documenting purity and key specifications are available for all shipments. We support customer audits and can provide material tailored to meet specific regulatory or application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15-25°C (59-77°F). Due to the highly volatile and flammable nature of the ethanol solvent, keep away from heat, sparks, and open flame. The container must be kept tightly sealed when not in use to prevent evaporation and moisture absorption.
