Description

Butylzinc Bromide is an organozinc reagent, a versatile and highly reactive intermediate for organic synthesis. This compound is valued for its role in facilitating carbon-carbon bond formation, particularly in cross-coupling reactions and nucleophilic additions. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors seeking to develop novel compounds and fine chemicals.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) and complex drug molecules.
• Agrochemical Synthesis: Used in the production of pesticides, herbicides, and plant growth regulators.
• Cross-Coupling Reactions: Serves as a nucleophilic reagent in Negishi and related cross-coupling reactions to form new C-C bonds.
• Organic Synthesis Reagent: Employed in laboratories and pilot plants for nucleophilic addition to carbonyl compounds and other electrophiles.
• Advanced Material Precursor: Used in the research and development of specialty polymers and functional materials.
• Catalyst and Ligand Preparation: Acts as a precursor for the synthesis of organometallic catalysts and ligands.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and concentration, typically provided as a solution in a specified organic solvent. Certificates of Analysis (COA) detailing assay results, solvent content, and impurity profiles are available upon request. We adhere to strict in-house quality protocols suitable for research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Due to its properties of being easily oxidized (store under inert atmosphere), hygroscopic (moisture-sensitive), and highly volatile, it is recommended to store at temperatures between 2°C and 8°C. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and oxidizing agents.
