Parachlorotoluene

Parachlorotoluene is an organic compound with the chemical formula ClC6H4CH3. It is a substituted toluene, meaning a chlorine atom is attached to the benzene ring of toluene. There are three possible positional isomers for parachlorotoluene, depending on where the chlorine atom is attached relative to the methyl group: ortho-chlorotoluene, meta-chlorotoluene, and para-chlorotoluene. This article refers specifically to the para isomer, where the chlorine atom is opposite the methyl group on the ring.

Parachlorotoluene is a colorless liquid or crystalline solid with a distinct odor. It is largely insoluble in water but soluble in many organic solvents like ethanol and ether. It is flammable and can be irritating to skin and eyes.

The compound is typically produced through the chlorination of toluene. It serves as an intermediate in the synthesis of various other chemicals, including dyes, pharmaceuticals, and pesticides. Its specific uses depend on the desired end product and the reactions it undergoes. Like many chlorinated organic compounds, its environmental persistence and potential toxicity are subjects of consideration.
