TCI C0877 2-Chloro-5-nitrobenzoic Acid (CAS 2516-96-3) is a trifunctional aromatic building block combining a carboxylic acid, an aryl chloride, and a nitro group on a single benzene ring. The strongly electron-withdrawing nitro group activates the chlorine towards nucleophilic aromatic substitution, while the carboxylic acid readily forms esters and amides. It is routinely used in pharmaceutical intermediate synthesis, dye chemistry, and the construction of fused heterocyclic systems. AMI Scientific offers this TCI product in 25 g and 500 g packs suitable for both exploratory and repeated preparative work.
