Description

Methyl 3-Bromobenzoate CAS NO 618-89-3 is a high-purity organic ester derivative of 3-bromobenzoic acid, serving as a versatile and critical building block in advanced chemical synthesis. Its value lies in providing a protected carboxylic acid group and a reactive bromine substituent, enabling precise molecular construction. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require reliable intermediates for developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a benzoate ester moiety with halogen functionality for further coupling reactions.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and insecticides where the bromine atom allows for selective functionalization.
• Liquid Crystal & OLED Material Production: Acts as a starting material for creating complex aromatic esters used in electronic displays and organic light-emitting diodes.
• Polymer Chemistry: Employed as a monomer or chain modifier in the production of specialty polymers and resins with specific thermal or optical properties.
• Organic Synthesis & Research: A valuable reagent in cross-coupling reactions (e.g., Suzuki, Heck) and as a protecting group strategy in multi-step laboratory syntheses.
• Dye & Pigment Manufacturing: Intermediate for synthesizing brominated aromatic dyes and colorants.
