ClCH2CH2CH2CH3

ClCH2CH2CH2CH3, also known as 1-chlorobutane or n-butyl chloride, is an organochlorine compound with the chemical formula C4H9Cl. It is a colorless liquid at room temperature with a characteristic ethereal odor. 1-chlorobutane is structurally a butane molecule where one of the terminal hydrogen atoms has been replaced by a chlorine atom.

This compound is primarily used as a solvent and as an intermediate in the synthesis of other organic chemicals. It can be employed in the production of organometallic reagents, such as Grignard reagents, and in various alkylation reactions. Its solubility properties make it useful in certain industrial processes and laboratory applications.

1-chlorobutane is flammable and should be handled with care. It is generally considered to have moderate toxicity. Exposure can occur through inhalation, skin contact, or ingestion. Appropriate safety precautions, including adequate ventilation and personal protective equipment, are recommended when working with this substance. It is important to store 1-chlorobutane in a cool, well-ventilated area away from sources of ignition.
