2-Chlorobenzoic acid

Description:

2-Chlorobenzoic acid is an aromatic carboxylic acid characterized by the presence of a chlorine atom at the second position of the benzene ring relative to the carboxylic acid group. Its molecular formula is C7H5ClO2, and it features a carboxyl functional group (-COOH) that imparts acidic properties. This compound typically appears as a white crystalline solid and is sparingly soluble in water, but more soluble in organic solvents such as ethanol and ether. 2-Chlorobenzoic acid is known for its applications in organic synthesis, particularly as an intermediate in the production of pharmaceuticals, agrochemicals, and dyes. It can undergo various chemical reactions, including esterification and nucleophilic substitution, due to the reactivity of both the carboxylic acid and the chlorine substituent. Additionally, it exhibits moderate toxicity, necessitating appropriate safety measures during handling and use. Overall, 2-chlorobenzoic acid is a significant compound in both industrial and research settings due to its versatile chemical properties.
