2Chloronaphthalene

2-Chloronaphthalene is an organic compound with the chemical formula C10H7Cl. It is a chlorinated derivative of naphthalene, a bicyclic aromatic hydrocarbon. In its pure form, 2-chloronaphthalene is typically a white crystalline solid. It has a molecular weight of approximately 162.62 g/mol. The compound is generally insoluble in water but soluble in many organic solvents such as ethanol, ether, and benzene. Its melting point is around 53-56 degrees Celsius. 2-Chloronaphthalene can be synthesized through various chemical routes, often involving the direct chlorination of naphthalene under specific conditions to favor substitution at the 2-position. It has found limited use in certain industrial applications, historically including as a dielectric fluid and as an intermediate in the synthesis of dyes and other organic chemicals. However, its environmental persistence and potential toxicity have led to a decline in its widespread use. Like other chlorinated aromatic hydrocarbons, 2-chloronaphthalene is considered a persistent organic pollutant (POP) and its presence in the environment is a concern due to its potential for bioaccumulation and adverse effects on ecosystems and human health. Consequently, its production and use are subject to regulatory scrutiny in many regions.
