Description

Chlorotriphenylsilane is a versatile organosilicon reagent featuring a reactive silicon-chlorine bond. This compound is a critical building block in organic synthesis, valued for its ability to introduce the triphenylsilyl protecting group or serve as a precursor to other functional silanes. It is essential for manufacturers and R&D chemists in the pharmaceutical, agrochemical, and advanced materials sectors. Chlorotriphenylsilane, CAS NO 155684-37-0, enables precise molecular modifications under controlled conditions.

Application

• Protecting Group Agent: Widely used for the protection of alcohols, diols, and phenols in multi-step organic synthesis, particularly in pharmaceutical intermediate manufacturing.
• Silicon-Based Polymer Synthesis: Serves as a monomer or chain-transfer agent in the production of specialized silicones and siloxane polymers with unique thermal and mechanical properties.
• Surface Modification: Employed to functionalize silica, glass, and other inorganic surfaces to alter hydrophobicity, adhesion, or biocompatibility.
• Catalyst and Ligand Precursor: Used to synthesize organosilicon ligands for transition metal catalysis and as a reagent in Lewis acid-catalyzed reactions.
• Electronics and Semiconductor Industry: Acts as a precursor in chemical vapor deposition (CVD) processes for depositing silicon-containing thin films.
• Agrochemical Intermediate: Utilized in the synthesis of certain silicon-containing active ingredients and formulation additives.

Quality Control

Our Chlorotriphenylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and impurity profiling, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and physical properties 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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity.
