Description

Chlorotriethylsilane is a versatile organosilicon reagent primarily used as a silylating agent and a key intermediate in organic synthesis. Its value lies in its ability to introduce the triethylsilyl (TES) protecting group, offering a balance of stability and ease of removal under mild conditions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where precise molecular modification is required. Global industries rely on its consistent quality for developing active ingredients and functional silanes.

Application

• As a protecting group reagent for alcohols, phenols, and carboxylic acids in multi-step organic synthesis.
• Key intermediate in the production of more complex silicon-based compounds and functionalized silanes.
• Used in the manufacture of pharmaceutical intermediates and active pharmaceutical ingredients (APIs).
• Employed as a precursor in surface modification and the synthesis of silicone polymers.
• Facilitates agrochemical synthesis for the development of herbicides and pesticides.
• Utilized in material science research for creating specialized coatings and adhesives.

Quality Control

Our Chlorotriethylsilane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including GC, NMR, and titration methods, to meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and ignition sources. Due to its moisture-sensitive (hygroscopic) nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids and organic solvents.
