Quality Control

Our Phenylthiotrimethylsilane is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and Karl Fischer titration to confirm identity, potency, and moisture content. A comprehensive Certificate of Analysis (COA) detailing all test results 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, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed and may require handling under an inert atmosphere for critical applications.
