13dichloropropane

The compound 1,3-dichloropropane, also known as 13dichloropropane, is a chlorinated hydrocarbon with the molecular formula C3H6Cl2. It consists of a propane chain in which chlorine atoms are attached to the first and third carbons. The molecule is a colorless, odorless liquid at room temperature, with a modest boiling point of approximately 113 °C and a density near 1.1 g cm−3. Its physical properties are typical of small chlorinated alkanes, giving it limited volatility and moderate solubility in polar solvents.

Synthetic routes to 1,3-dichloropropane generally involve chlorination of propylene or the halogenation of 1,3-butadiene followed by a selective reduction step. Commercial production is largely driven by demand for intermediate reagents in organic synthesis, particularly in the preparation of alkylating agents and as a source of dihalogenated carbon skeletons for polymerizable monomers.

Industrial and laboratory uses of the compound include serving as a reactant in the synthesis of heterocycles, as a solvent in certain specialized processes, and occasionally as a pesticide precursor in the manufacturing of certain agrochemical intermediates. Because of its reactivity, it is handled by professionals with access to appropriate containment equipment.

Safety data indicate that the chemical is a moderate irritant to the skin, eyes, and respiratory tract. Prolonged exposure may lead to systemic toxicity, and some studies suggest potential carcinogenicity via metabolic activation. Accordingly, many regulatory bodies classify it as hazardous; for example, it is listed under the REACH regulation in the European Union and is subject to restrictions in occupational exposure settings. Proper personal protective equipment, ventilation, and spill containment are required to mitigate risks during its use and storage.
