chlorotoluene

Chlorotoluene is a group of aromatic organic compounds with the chemical formula C7H7Cl. These compounds are derived from toluene, which is methylbenzene, by replacing one hydrogen atom on the benzene ring with a chlorine atom. There are three possible isomers of chlorotoluene, differing in the position of the chlorine atom relative to the methyl group: ortho-chlorotoluene (o-chlorotoluene), meta-chlorotoluene (m-chlorotoluene), and para-chlorotoluene (p-chlorotoluene). Each isomer has distinct physical and chemical properties.

Ortho-chlorotoluene has the chlorine atom at the position adjacent to the methyl group. Meta-chlorotoluene has the chlorine atom at the position separated by one carbon atom from the methyl group. Para-chlorotoluene has the chlorine atom directly opposite the methyl group. Chlorotoluenes are generally colorless liquids with a characteristic odor. They are sparingly soluble in water but miscible with many organic solvents.

These compounds find various applications in the chemical industry. They serve as intermediates in the synthesis of dyes, pharmaceuticals, pesticides, and other organic chemicals. For instance, p-chlorotoluene is used in the production of p-chlorobenzaldehyde, which is a precursor for certain agrochemicals. The specific isomer and its purity are important factors for its intended application. Due to their chemical nature, chlorotoluenes should be handled with appropriate safety precautions.
