Quality Control

Our Trisilane, 1,1,1,3,3,3-Hexamethyl-2-Phenyl-2-(Trimethylsilyl)- is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including NMR, GC, and GC-MS. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity and key impurity profiles to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its moisture-sensitive and easily oxidized nature, the container must be kept sealed under positive pressure of inert gas. Recommended storage temperature is 2-8°C for long-term stability.
