Description

(Bromomethyl)Methyldichlorosilane CAS NO 16532-03-9 is a highly reactive organosilicon compound featuring both bromomethyl and dichlorosilyl functional groups, making it a versatile intermediate for advanced material synthesis. Its core value lies in enabling precise molecular modifications and serving as a key building block for silicon-based polymers and surface modifiers. This chemical is essential for R&D and production teams in the specialty chemical, pharmaceutical, and advanced materials sectors seeking to develop novel silane coupling agents, silicone precursors, or functionalized polymers.

Application

• Silane Coupling Agent Precursor: Used to synthesize specialized silane coupling agents for enhancing adhesion between organic polymers and inorganic surfaces like glass, metals, or minerals.
• Silicone Polymer Modification: Serves as a reactive monomer or cross-linking agent in the production of modified silicones with specific bromo-alkyl functionality for further derivatization.
• Pharmaceutical Intermediate: Acts as a key building block in the synthesis of complex molecules for active pharmaceutical ingredients (APIs) or diagnostic agents.
• Surface Functionalization: Employed to introduce reactive bromomethyl groups onto silicon or silica-based surfaces for subsequent attachment of biomolecules, catalysts, or other functional moieties.
• Hybrid Material Synthesis: A critical component in creating organic-inorganic hybrid materials, such as silsesquioxanes or functionalized sol-gel coatings.
• Polymer Cross-linking Agent: Utilized to introduce cross-links into polymer chains, improving thermal stability, chemical resistance, or mechanical properties.

Quality Control

Our (Bromomethyl)Methyldichlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets high-purity standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and highly volatile; ensure containers are kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation and moisture ingress. Keep away from strong acids, bases, and oxidizing agents.
