4-Chlorobenzene-1,3-dicarboxylic acid, with the CAS number 2845-85-4, is an aromatic dicarboxylic acid characterized by the presence of two carboxylic acid groups (-COOH) attached to a chlorinated benzene ring. The chlorine atom is positioned at the para position relative to one of the carboxylic acid groups, influencing the compound's reactivity and solubility. This substance typically appears as a white to off-white crystalline solid and is soluble in polar solvents such as water and alcohols, while being less soluble in non-polar solvents. It exhibits acidic properties due to the carboxylic groups, allowing it to participate in various chemical reactions, including esterification and amidation. The presence of the chlorine substituent can also enhance the compound's electrophilic character, making it useful in organic synthesis and as an intermediate in the production of pharmaceuticals, agrochemicals, and dyes. Additionally, its structural features may impart specific biological activities, warranting further investigation in medicinal chemistry.
