Quality Control

Our Phenyldichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) and handle in a dry environment to prevent hydrolysis. Keep away from strong bases and oxidizing agents.
