Description

(1-Bromoethyl)Benzene CAS NO 585-71-7 is a versatile organic halide building block, primarily valued for its reactive benzylic bromide functionality. This compound is essential for introducing the phenethyl moiety into more complex molecular architectures via nucleophilic substitution or metal-catalyzed cross-coupling reactions. It is a critical intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors seeking to develop new active ingredients and specialty chemicals.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing phenethylamine or substituted ethylbenzene cores.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that require ethylbenzene derivatives.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing specialized phosphine or nitrogen-based ligands used in homogeneous catalysis.
• Material Science Research: Employed in the development of liquid crystals, organic semiconductors, and polymers where precise aromatic alkylation is necessary.
• Organic Synthesis Reagent: Utilized in Grignard reagent formation, Friedel-Crafts alkylations, and other carbon-carbon bond-forming reactions in fine chemical production.
• Flavor and Fragrance Industry: Intermediate for the synthesis of certain aromatic compounds used in fragrance formulations.
