C8H7Cl

C8H7Cl, also known as 2-chloronaphthalene, is an organic compound with the molecular formula C8H7Cl. It is a chlorinated derivative of naphthalene, a polycyclic aromatic hydrocarbon. The chlorine atom is attached to the 2-position of the naphthalene ring system. C8H7Cl is a colorless to pale yellow liquid at room temperature, with a characteristic odor. It is sparingly soluble in water but soluble in organic solvents such as ethanol, acetone, and benzene.

C8H7Cl is primarily used as an intermediate in the synthesis of various organic compounds. It can undergo substitution reactions with nucleophiles, such as amines and alcohols, to form a wide range of derivatives. Additionally, it can be used in the preparation of dyes, pigments, and other chemicals. Due to its potential health and environmental hazards, the use of C8H7Cl is regulated, and its handling requires appropriate safety measures.

C8H7Cl is also a known environmental contaminant, as it can persist in soil and water for extended periods. Its potential to bioaccumulate in aquatic organisms and its potential toxicity to wildlife have raised concerns about its environmental impact. Research is ongoing to better understand the environmental fate and effects of C8H7Cl, as well as to develop more environmentally friendly alternatives to its use.
