Description

Crotylmagnesium Chloride is a versatile organometallic reagent, specifically a Grignard reagent, widely used in organic synthesis. Its primary value lies in its ability to act as a powerful nucleophile for the formation of new carbon-carbon bonds, introducing the crotyl group into target molecules. This makes it an essential intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries, where it is employed in the synthesis of complex molecules, active pharmaceutical ingredients (APIs), and specialty chemicals.

Application

• Pharmaceutical Synthesis: A key building block for constructing complex molecular frameworks in the development of active pharmaceutical ingredients (APIs) and drug candidates.
• Agrochemical Manufacturing: Used in the synthesis of advanced crop protection agents, herbicides, and fungicides.
• Fine Chemical Production: Essential for creating specialty chemicals, flavors, fragrances, and advanced material precursors.
• Organic Synthesis Research: A fundamental reagent in academic and industrial R&D labs for nucleophilic addition reactions, including 1,2- and 1,4-additions.
• Polymer Chemistry: Employed as an initiator or modifying agent in the synthesis of specialized polymers and elastomers.
• Stereoselective Synthesis: Utilized in reactions where control over the geometry (E/Z isomers) of the introduced alkene is crucial.

Quality Control

Our Crotylmagnesium Chloride is produced and handled under stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity, consistency, and reliable performance in synthetic applications. Standard quality parameters include assay by titration and verification of solution concentration. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature as a highly volatile and moisture-sensitive organometallic reagent, it 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. Keep away from heat, sparks, open flames, and incompatible materials such as water, acids, and oxidizing agents.
