Description

3-Bromopropyltrichlorosilane is a bifunctional organosilicon compound featuring both a reactive trichlorosilyl group and a bromopropyl moiety. This unique structure makes it a versatile and valuable silane coupling agent and chemical intermediate for introducing functional groups onto inorganic and organic substrates. It is essential for manufacturers and R&D laboratories in the silicone polymers, surface modification, and pharmaceutical synthesis sectors seeking to enhance material compatibility and create advanced hybrid materials.

Application

• Silane Coupling Agent: Used to modify glass, silica, and other mineral surfaces to improve adhesion with organic polymers in composites and coatings.
• Silicone Intermediate: Serves as a key precursor in the synthesis of specialized silicone oils, resins, and elastomers with bromoalkyl functionality.
• Surface Functionalization: Applied to create self-assembled monolayers (SAMs) on silicon wafers and other substrates for microelectronics and sensor applications.
• Organic Synthesis Building Block: The reactive bromine atom allows for further chemical transformations, making it useful in pharmaceutical and agrochemical intermediate synthesis.
• Crosslinking Agent: Employed in the production of crosslinked polymer networks and moisture-curable materials.
• Adhesion Promoter: Enhances the bond strength in sealants, adhesives, and primers, particularly on difficult-to-bond surfaces.

Quality Control

Our 3-Bromopropyltrichlorosilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and NMR, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its moisture-sensitive and highly volatile nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) and handled in a fume hood. Recommended storage temperature: 2-8°C.
