Description

4-Bromobutyltrichlorosilane is a versatile organosilicon reagent featuring both a reactive bromoalkyl chain and hydrolyzable trichlorosilyl groups. This bifunctional nature makes it a critical intermediate for introducing silyl-protected organic functionalities into advanced materials and complex molecules. It is primarily sought by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for applications in surface modification, cross-linking, and as a building block in organic synthesis.

Application

• Surface Modification Agent: Used to functionalize silica, glass, and other metal oxide surfaces, creating hydrophobic or reactive coatings.
• Polymer Cross-Linker: Serves as a coupling agent or cross-linking monomer in the synthesis of silicone-based polymers and hybrid organic-inorganic materials.
• Pharmaceutical Intermediate: Acts as a key synthon for constructing drug molecules that incorporate silicon or require specific alkyl chain modifications.
• Agrochemical Synthesis: Employed in the production of advanced pesticides and herbicides where silane groups enhance stability or bioavailability.
• Adhesive & Sealant Formulations: Improves adhesion to various substrates in high-performance silicone adhesive and sealant systems.
• Chromatography Media: Utilized to derivatize stationary phases for HPLC and GC columns, tailoring separation selectivity.
• Nanomaterial Synthesis: Functions as a precursor or capping agent in the sol-gel process for creating functionalized nanoparticles.

Quality Control

Our production of 4-Bromobutyltrichlorosilane adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed via GC, NMR, and titration methods to confirm identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your material specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area 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) after opening to prevent hydrolysis. Keep away from strong bases, oxidizing agents, and sources of ignition.
