Description

Bromoethylbenzene CAS NO 31620-80-1 is a versatile aromatic halide compound, specifically a brominated derivative of ethylbenzene. This chemical serves as a critical alkylating agent and synthetic intermediate in advanced organic synthesis, enabling the introduction of the phenethyl moiety into target molecules. It is essential for manufacturers and R&D teams in the pharmaceutical, agrochemical, and specialty chemical sectors who require high-purity building blocks for complex molecule construction.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a phenethylamine or substituted ethylbenzene backbone.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and pesticides where its aromatic bromine functionality allows for further selective coupling reactions.
• Liquid Crystal & OLED Material Precursor: Serves as an intermediate in the manufacture of specialty chemicals for electronic displays and organic light-emitting diodes.
• Organic Synthesis Reagent: Employed as an alkylating agent in Friedel-Crafts and nucleophilic substitution reactions to introduce the 2-phenylethyl group.
• Fragrance & Flavor Intermediate: Utilized in the controlled synthesis of specific aromatic compounds for specialty fragrance and flavor applications.
• Polymer Modification: Acts as a functional monomer or cross-linking agent in the production of specialty polymers and resins.
