Quality Control

Our production of Silane, [(2-Ethylphenyl)Ethynyl]Trimethyl- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and purity for demanding synthetic applications. Each lot undergoes comprehensive analysis using techniques such as GC, HPLC, NMR, and FTIR. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material must be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flame.
