Description

Allylmagnesium Bromide is a versatile organometallic reagent, specifically a Grignard reagent, widely used in organic synthesis for its ability to introduce the allyl group. Its high reactivity under controlled conditions makes it a critical building block for constructing complex molecular frameworks. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where precise carbon-carbon bond formation is required.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for introducing the allyl moiety in the production of active pharmaceutical ingredients (APIs) and fine chemicals.
• Agrochemical Manufacturing: Used in the synthesis of herbicides, fungicides, and other crop protection agents that require allylic structures.
• Polymer & Material Science: Serves as a monomer or functionalization agent in the development of specialty polymers and advanced materials.
• Organic Synthesis & Research: Fundamental tool in academic and industrial R&D labs for nucleophilic addition reactions to carbonyl compounds (aldehydes, ketones, esters).
• Flavor & Fragrance Industry: Employed in the synthesis of certain terpenes and other aromatic compounds.
• Cross-Coupling Reactions: Acts as a coupling partner in various transition metal-catalyzed reactions to form new carbon-carbon bonds.

Quality Control

Our Allylmagnesium Bromide is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including titration for assay determination and GC analysis for solvent and impurity profiling, to ensure consistency and high purity suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee reliable performance and traceability.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this product must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for extended stability. Keep away from heat, sparks, open flames, and incompatible materials such as moisture, acids, and oxidizing agents.
