Description

1-Ethylpentylzinc Bromide is a highly reactive organozinc reagent, specifically an alkylzinc bromide. This compound is a valuable synthetic intermediate in organic chemistry, prized for its ability to transfer the 1-ethylpentyl group in cross-coupling and nucleophilic addition reactions. It is primarily utilized by researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors for the construction of complex carbon frameworks.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs) via Negishi and related cross-coupling reactions.
• Agrochemical Synthesis: Used in the production of novel pesticides and herbicides that require specific branched alkyl chain motifs.
• Advanced Material Precursor: Serves as an organometallic precursor in the development of specialized polymers and functional materials.
• Fine Chemical Manufacturing: Employed in the scalable synthesis of complex organic molecules for flavors, fragrances, and electronic chemicals.
• Catalysis Research: A reagent in methodological development for new metal-catalyzed C-C bond formation processes.
• Asymmetric Synthesis: Used in conjunction with chiral ligands to create stereogenic centers in target molecules.

Quality Control

Our 1-Ethylpentylzinc Bromide is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm identity, purity, and concentration, typically supplied as a solution in a specified organic solvent. A comprehensive Certificate of Analysis (COA) detailing assay (by titration), solvent content, and impurity profile is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at recommended cold temperatures (e.g., 2-8°C or as specified for the solution) to maintain stability and prevent decomposition. The material is highly volatile, easily oxidized, and hygroscopic; all handling must be conducted under anhydrous, oxygen-free conditions using appropriate Schlenk or glovebox techniques.
