Cyclohexylmagnesium chloride solution
Cyclohexylmagnesium chloride solution (CAS 931-51-1), with the empirical formula C6H11ClMg and a molecular weight of 142.91 g/mol, is a potent organometallic reagent. It is supplied as a 1.0 M solution in 2-methyltetrahydrofuran. This Grignard reagent is crucial for introducing the cyclohexyl group in organic synthesis, particularly in the formation of carbon-carbon bonds in pharmaceutical and fine chemical production.

Grignard Reagent in Organic Synthesis
Utilised for nucleophilic addition reactions, Cyclohexylmagnesium chloride solution is a key reagent for forming new carbon-carbon bonds. It is widely applied in the synthesis of complex organic molecules and intermediates.
Pharmaceutical Intermediate Synthesis
This compound serves as a building block in the multi-step synthesis of active pharmaceutical ingredients (APIs). Its reactivity allows for the efficient construction of cyclohexyl-containing pharmacophores.
Fine Chemical Production
Employed in the manufacture of fine chemicals where the introduction of a cyclohexyl moiety is required. Its application extends to the development of novel materials and specialty chemicals.
