Description

Benzylzinc Bromide is a highly reactive organozinc reagent, specifically a benzylzinc halide, with the CAS registry number 62673-31-8. This compound is a critical intermediate for introducing the benzyl group in advanced organic synthesis, offering superior chemoselectivity compared to traditional Grignard reagents. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate Synthesis: Key building block for the production of active pharmaceutical ingredients (APIs), particularly in cross-coupling reactions.
• Agrochemical Manufacturing: Used in the synthesis of advanced herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Enables the efficient benzylation of carbonyl compounds, halides, and other electrophiles in specialty chemical routes.
• Material Science Research: Serves as a precursor in the development of novel organometallic complexes and catalysts.
• Negishi Cross-Coupling Reactions: An essential reagent for forming carbon-carbon bonds between benzyl groups and aryl or vinyl halides.
• Asymmetric Synthesis: Employed in stereoselective transformations for the synthesis of chiral molecules.
