13dichlorobenzene

Note: The term 13dichlorobenzene is not a standard designation; the conventional name for this compound is 1,3-dichlorobenzene, also called m-dichlorobenzene.

1,3-Dichlorobenzene is an organic compound in which two chlorine atoms are substituted on a benzene ring at the 1 and 3 positions. It is one of three isomers of dichlorobenzene.

Industrial production involves the chlorination of benzene or chlorobenzenes, yielding a mixture of dichlorobenzenes that are separated by distillation or crystallization to isolate the 1,3‑isomer.

Physically, 1,3-dichlorobenzene is a colorless liquid or solid depending on temperature, with limited water solubility and good solubility in organic solvents.

Uses include serving as an intermediate in the manufacture of agrochemicals, dyes, and polymers, as well as a solvent or reaction medium in chemical synthesis.

Safety and environmental considerations: It is hazardous if inhaled or absorbed through the skin; exposure can irritate the eyes, skin, and respiratory tract, and long-term exposure may be harmful. It is relatively persistent in the environment and should be contained in spills; wastewater disposal must follow local regulations.
