CH2ClCH2CH2Cl

1,3-Dichloropropane is an organochlorine compound with the chemical formula CH2ClCH2CH2Cl. It is a colorless liquid with a somewhat sweet odor. This compound is a dichloroalkane, meaning it contains two chlorine atoms bonded to a three-carbon propane chain. It is structurally similar to propane, with chlorine atoms replacing hydrogen atoms on the terminal carbon atoms.

1,3-Dichloropropane is typically produced through the chlorination of propane or through the reaction of allyl chloride with hydrogen chloride. It finds limited applications primarily as a chemical intermediate in the synthesis of other organic compounds. Historically, it has been used in some specialty solvents and as a fumigant, although these uses have largely been discontinued due to environmental and health concerns.

Due to the presence of chlorine atoms, 1,3-dichloropropane is considered to be a moderately toxic substance. Exposure can occur through inhalation, skin contact, or ingestion. It is important to handle this chemical with appropriate safety precautions, including adequate ventilation and personal protective equipment. Its environmental persistence and potential for bioaccumulation are also factors that contribute to its restricted use.
