Quality Control

Our Butyltrimethylsilane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to rigorous analytical testing, including GC and NMR analysis, to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
