Description

3,4-Dichlorobenzylmagnesium Chloride is a highly reactive organometallic reagent, specifically a Grignard reagent, essential for forming new carbon-carbon bonds in complex organic syntheses. Its value lies in its ability to introduce the 3,4-dichlorobenzyl moiety into target molecules, a key step in constructing advanced intermediates. This compound is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the production of active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate Synthesis: A critical building block for constructing complex molecules used in active pharmaceutical ingredients (APIs), particularly those requiring the 3,4-dichlorobenzyl functional group.
• Agrochemical Manufacturing: Used in the synthesis of advanced herbicides, fungicides, and insecticides where the dichlorinated benzyl structure imparts specific biological activity.
• Material Science Research: Employed in the development of novel organic materials, liquid crystals, and polymers through controlled polymerization or functionalization reactions.
• Fine Chemical Production: Serves as a versatile reagent for the custom synthesis of specialty chemicals, dyes, and flavor/fragrance compounds.
• Academic & R&D Laboratories: A valuable tool for methodological development in organic chemistry and for exploring new synthetic pathways in discovery research.

Quality Control

Our 3,4-Dichlorobenzylmagnesium Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high reactivity. Each lot is analyzed to confirm concentration, purity, and suitability for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing assay (by titration), solvent content, and impurity profile is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive and moisture-sensitive nature, this product must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures, typically between 2°C and 8°C for extended stability. The container must be kept in a cool, dry, well-ventilated area away from incompatible materials.
