C3H7Cl, also known as propyl chloride, is an organic compound that consists of three carbon atoms, seven hydrogen atoms, and one chlorine atom. It is classified as an alkyl halide, which means it contains a halogen atom (in this case, chlorine) attached to a carbon chain. Propyl chloride is often used as a solvent and in the production of other chemicals. This compound can exist in different structural forms, including n-propyl chloride and isopropyl chloride, which have distinct properties and uses. Propyl chloride is typically colorless and has a sweet odor. It is important to handle it with care due to its potential health hazards, including irritation to the skin and respiratory system.
