4-Chlorobenzonitrile
4-Chlorobenzonitrile (CAS: 623-03-0) is an aromatic nitrile combining a para-chloro substituent with a cyano group, supplied as a white to off-white crystalline solid. The two reactive positions enable both nucleophilic aromatic substitution at the halide and nitrile transformation to acids, amides, and amines, making it a versatile building block for pharmaceutical, agrochemical, and dye intermediates. The solid form stores and handles well as a stable crystalline powder. Customers select it where a bifunctional aromatic intermediate with clean conversion at either position is required for multi-step synthesis.
• Building block: a bifunctional aromatic with reactive chloro and cyano positions.
• Substitution: the para-chloride undergoes nucleophilic aromatic substitution with amines and phenoxides.
• Nitrile chemistry: converts to acids, amides, esters, and amines for downstream intermediates.
• Applications: used in pharmaceutical, agrochemical, and dye intermediate synthesis.
