3-Chloro-2-nitrobenzoic acid（Cat No.:L023202）is an aromatic carboxylic acid featuring a chlorine atom at the 3-position and a nitro group at the 2-position of a benzoic acid core. This compound is commonly used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and dyes. The presence of both electron-withdrawing substituents enhances the compound’s reactivity toward nucleophilic aromatic substitution and facilitates further functionalization. Its structural features support regioselective transformations, making it valuable in designing heterocycles and bioactive molecules. Additionally, it serves as a precursor for more complex aromatic and nitrogen-containing compounds.
