Description

(p-tert-Butylphenethyl)Dimethylchlorosilane is a specialized organosilicon compound, specifically a chlorosilane derivative, that serves as a critical building block in advanced organic synthesis. Its core value proposition lies in its dual functionality, where the reactive chlorosilyl group enables efficient silicon-carbon bond formation, while the bulky p-tert-butylphenethyl moiety provides steric and electronic influence. This compound is essential for researchers and manufacturers in the pharmaceutical and advanced materials sectors who require high-purity intermediates for creating novel silicon-containing molecules, such as ligands, surface modifiers, and functional polymers.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel active pharmaceutical ingredients (APIs) and drug candidates containing organosilicon groups.
• Surface Modification Agent: Used to functionalize silica, glass, and other inorganic surfaces to alter their hydrophobicity, adhesion, or biocompatibility.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the production of specialty silicones, siloxane-based polymers, and hybrid organic-inorganic materials.
• Catalyst & Ligand Synthesis: Employed in the preparation of sophisticated silicon-based ligands for transition metal catalysis and organocatalysts.
• Analytical Chemistry Reagent: Used as a derivatization agent in gas chromatography (GC) and mass spectrometry (MS) for the analysis of compounds with active hydrogens.
• Adhesive & Coating Formulations: Imparts specific properties like moisture resistance and improved bonding in high-performance adhesive and coating systems.

Quality Control

Our production of (p-tert-Butylphenethyl)Dimethylchlorosilane adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from strong bases and oxidizing agents.
