Description

tert-Butylphenyldichlorosilane is a highly reactive organosilicon compound, specifically a dichlorosilane derivative, widely used as a key intermediate in organosilicon chemistry. Its primary value lies in its ability to serve as a versatile building block for synthesizing more complex silanes, siloxanes, and silicone polymers with tailored properties. This chemical is essential for R&D chemists and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where it is utilized to introduce the tert-butylphenylsilyl group, a valuable moiety for protection and modification.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and as a protecting group for alcohols and other functional groups during complex multi-step syntheses.
• Agrochemical Synthesis: Serves as a precursor for creating silicon-containing pesticides, herbicides, and plant growth regulators.
• Silicone Polymer Modification: Acts as a monomer or cross-linking agent to introduce aromatic and bulky alkyl groups into silicone resins, impacting their thermal stability, refractive index, and mechanical properties.
• Surface Treatment Agent: Employed to modify inorganic surfaces like silica or metals, creating hydrophobic or specific functional coatings.
• Laboratory Reagent: A valuable reagent in academic and industrial research for exploring new organosilicon compounds and materials.
• Adhesive & Sealant Formulations: Used to develop high-performance silicone-based adhesives and sealants with enhanced characteristics.

Quality Control

Our tert-Butylphenyldichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request 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 hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature: 2-8°C (refrigerated).
