1,2-Dichloronaphthalene is an aromatic organic compound characterized by the presence of two chlorine atoms attached to a naphthalene ring at the 1 and 2 positions. It is a colorless to pale yellow liquid with a distinctive odor, and it is insoluble in water but soluble in organic solvents such as ethanol and ether. This compound is known for its relatively high boiling point and moderate volatility. It is primarily used as an intermediate in the synthesis of various chemicals, including dyes and pesticides, and can also serve as a solvent in industrial applications. 1,2-Dichloronaphthalene exhibits moderate toxicity, and exposure can lead to health effects, necessitating proper handling and safety precautions. Additionally, it is classified as a potential environmental pollutant, as it can persist in the environment and bioaccumulate in aquatic organisms. Its chemical structure contributes to its reactivity, making it a subject of study in both organic chemistry and environmental science.

1,2-Dichloronaphthalene is a naphthalene molecule with two chlorine atoms attached. It has an optical rotation of +29° and birefringence of 0.0022. The oxidant can be found in elemental sulfur or as a byproduct in the processing of silicone rubber, which has a red shift in its frequency range. 1,2-Dichloronaphthalene can also be used as an anion to form polysulfides. Exciton complexes are formed between silicon molecules when they are exposed to 1,2-dichloronaphthalene.

Applications 1,2-Dichloronaphthalene is an organic pollutant found in wastewater.
