Product Description:

2-Chloro-1,4-dimethylbenzene, also known as 2-chloro-p-xylene, is an organic compound with the molecular formula C8H9Cl. It is a colorless to pale yellow liquid at room temperature. Structurally, it is a chlorinated derivative of p-xylene, where a chlorine atom is substituted at the ortho position relative to one of the methyl groups on the benzene ring. This compound is primarily used as a versatile intermediate in organic synthesis. Its key applications include serving as a precursor for the synthesis of dyes, pigments, and other fine chemicals. The chlorine atom provides a reactive site for further functionalization through various coupling and substitution reactions. It is also employed as a starting material or building block in the synthesis of pharmaceuticals and agrochemicals, although its role is typically as a foundational chemical scaffold rather than a final active ingredient. As a halogenated aromatic compound, it requires careful handling. It is flammable and may cause skin and eye irritation. Proper personal protective equipment and adequate ventilation are recommended during its use in laboratory or industrial settings.
