Description

Ethylzinc Bromide, 0.50 M In Thf is a highly reactive organozinc reagent, supplied as a standardized solution in tetrahydrofuran for precise stoichiometric control in sensitive synthetic transformations. This compound is a critical precursor for the formation of carbon-carbon bonds, particularly in cross-coupling and nucleophilic addition reactions where its moderate reactivity offers superior selectivity. It is essential for R&D and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-purity organometallic intermediates.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for the preparation of complex molecules via Negishi-type cross-coupling reactions.
• Agrochemical Active Ingredient Production: Used in the synthesis of novel pesticides and herbicides requiring specific zinc-mediated bond formations.
• Advanced Material Development: Serves as a precursor for depositing zinc-containing thin films or creating novel organometallic frameworks in materials science.
• Fine Chemical and Catalyst Manufacturing: Employed in the production of specialty catalysts and ligands where ethyl group transfer is required.
• Academic and Industrial R&D: A fundamental tool for methodological development in organic and organometallic chemistry laboratories.
• Polymer Modification: Can be used to introduce ethyl-zinc functional groups into polymer chains for property modification.
