Hexylmagnesium bromide solution
Hexylmagnesium bromide solution (CAS: 3761-92-0), with the linear formula CH₃(CH₂)₅MgBr and a molecular weight of 189.38 g/mol, is a highly reactive organometallic compound. Supplied as a 2.0 M solution in diethyl ether, it functions as a potent nucleophile and base. Its primary applications lie in organic synthesis for introducing hexyl groups into molecules and in the formation of carbon-carbon bonds, making it an essential reagent in chemical research and development.

Grignard Reagent in Organic Synthesis
Hexylmagnesium bromide is a key Grignard reagent used to introduce a hexyl group via nucleophilic addition to carbonyl compounds (aldehydes, ketones, esters) and epoxides. This reaction is fundamental for constructing more complex organic molecules.
Alkylation Reactions
It serves as an effective alkylating agent, reacting with various electrophiles to form new carbon-carbon bonds. This capability is crucial in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals.
Formation of Organometallic Compounds
This reagent can be used in the synthesis of other organometallic species. Its reactivity allows for the preparation of diverse compounds essential for catalysis and materials science.
