Description

Phenylsilane CAS NO 694-53-1 is a versatile organosilicon compound characterized by a silicon-hydrogen (Si-H) bond directly attached to a phenyl group. This structure makes it a valuable reagent in synthetic chemistry, particularly for introducing the phenylsilane moiety into more complex molecules. It serves as a key intermediate and reducing agent in the production of advanced materials, including silicones, polymers, and electronic chemicals. Industries such as pharmaceuticals, agrochemicals, and specialty materials rely on its unique reactivity for precise chemical synthesis.

Application

• Silicone & Polymer Modification: Acts as a cross-linking agent or functional monomer in the synthesis of specialty silicones and phenyl-containing polymers.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and other complex organic molecules via hydrosilylation or reduction reactions.
• Surface Treatment & Coatings: Employed as a precursor for creating hydrophobic or adhesion-promoting layers on glass, metals, and other substrates.
• Semiconductor & Electronics: Serves as a silicon source in chemical vapor deposition (CVD) processes for thin-film and semiconductor manufacturing.
• Agrochemical Synthesis: Utilized in the production of certain pesticides and herbicides where the phenylsilane group is integral to the molecule's activity.
• Research & Development: A fundamental reagent in organometallic and materials science research for exploring new catalytic processes and material properties.

Quality Control

Our Phenylsilane is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including gas chromatography (GC) and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment. Our quality management system supports compliance with relevant industry standards for fine chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat and ignition sources. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert gas such as nitrogen or argon. Keep container tightly sealed when not in use to prevent moisture ingress and evaporation. Recommended storage temperature is 2-8°C for extended stability.
