Description

Di-n-Butylmagnesium is a highly reactive organomagnesium compound, commonly utilized as a versatile alkylating agent and a powerful Grignard-type reagent in organic synthesis. Its primary commercial value lies in its ability to introduce butyl groups and act as a strong base for deprotonation reactions, enabling the production of complex molecules. This chemical is essential for R&D laboratories and industrial-scale manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors seeking efficient pathways for carbon-carbon bond formation.

Application

• Pharmaceutical Intermediate Synthesis: A key reagent for constructing active pharmaceutical ingredients (APIs) through nucleophilic addition and substitution reactions.
• Agrochemical Manufacturing: Used in the synthesis of herbicides, fungicides, and pesticides that require specific butyl-substituted structures.
• Polymer & Catalyst Production: Serves as a co-catalyst or initiator in Ziegler-Natta type polymerization systems and for modifying catalyst surfaces.
• Fine Chemical Production: Employed in the preparation of specialty chemicals, flavors, and fragrances where precise alkylation is critical.
• Organic Synthesis Research: A fundamental tool in academic and industrial R&D for exploring new synthetic methodologies and creating novel organic compounds.
• Electrolyte Additive for Batteries: Investigated for use in electrolyte formulations to improve the performance and stability of advanced battery systems.

Quality Control

Our Di-n-Butylmagnesium is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and high reactivity. Quality is verified through analytical techniques including titration (for active magnesium content) and gas chromatography (for solvent and hydrocarbon purity). A comprehensive Certificate of Analysis (COA) detailing assay, concentration, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is highly moisture-sensitive (hygroscopic) and typically supplied and stored under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area. For long-term stability, store at temperatures between 2°C and 8°C. Keep away from heat, sparks, open flames, and incompatible materials such as water, acids, and oxidizing agents.
