Description

Propanoicacid, 2-Bromo-2-Methyl-, 3-(Ethoxydimethylsilyl)Propyl Ester is a specialized organosilicon compound that serves as a versatile intermediate and functional monomer. This chemical is engineered to provide a unique combination of a reactive bromoester group and a hydrolyzable ethoxysilane moiety, enabling covalent bonding to inorganic surfaces and polymer backbones. It is primarily sought by manufacturers in the silicone polymer, advanced coatings, and adhesive industries for developing materials with enhanced adhesion, cross-linking density, and tailored surface properties.

Application

• Silicone Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce reactive bromoester sites into silicone resins, enhancing compatibility with organic polymers or enabling further chemical derivatization.
• Surface Primers & Adhesion Promoters: Used in formulations for primers on glass, metals, and minerals, where the silane group bonds to the substrate and the bromoester functionality provides an anchor for subsequent coating layers.
• Hybrid Organic-Inorganic Materials (ORMOSILs): A key precursor in sol-gel processes for creating optically clear, scratch-resistant coatings with specific reactive handles for post-functionalization.
• Controlled Release & Drug Delivery Systems: Employed in the synthesis of silane-based prodrugs or biodegradable polymer matrices where the bromoester can be used for attaching active pharmaceutical ingredients (APIs).
• Specialty Adhesives & Sealants: Incorporated to improve the adhesion of silicone-based sealants to challenging substrates and to increase the thermal and chemical resistance of the cured product.
• Research & Chemical Synthesis: Serves as a valuable building block in organic and polymer chemistry for introducing both silyl-protected and alkyl halide functionalities in a single molecule.

Quality Control

Our production of Propanoicacid, 2-Bromo-2-Methyl-, 3-(Ethoxydimethylsilyl)Propyl Ester adheres to a stringent quality management system. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, 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 area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers should be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
