1,2-Dichlorobenzene(CAT: R021777), also known as ortho-dichlorobenzene, is a chlorinated aromatic hydrocarbon consisting of two chlorine atoms substituted at adjacent positions on a benzene ring. It is a colorless to pale yellow liquid with a pleasant, penetrating odor and is widely used as a solvent for waxes, resins, and degreasing agents. In chemical synthesis, it serves as an intermediate for dyes, agrochemicals, and pharmaceuticals. Its thermal stability and solvent properties make it valuable in high-temperature applications. Additionally, 1,2-dichlorobenzene is used in the production of specialty polymers and as a precursor for more complex chlorinated aromatic compounds.
