2-Methylpentanoyl chloride

Description:
2-Methylpentanoyl chloride, with the CAS number 5238-27-7, is an acyl chloride derived from 2-methylpentanoic acid. It is characterized by the presence of a carbonyl group (C=O) bonded to a chlorine atom, making it a reactive compound commonly used in organic synthesis. This substance typically appears as a colorless to pale yellow liquid with a pungent odor, indicative of its reactivity and potential to release hydrochloric acid upon hydrolysis. 2-Methylpentanoyl chloride is soluble in organic solvents such as dichloromethane and ether but reacts vigorously with water, leading to the formation of the corresponding acid and hydrochloric acid. Its reactivity allows it to participate in various chemical reactions, including acylation and the formation of amides and esters. Due to its corrosive nature, it requires careful handling and storage under inert conditions to prevent moisture exposure. Overall, 2-methylpentanoyl chloride is a valuable intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds.
