4-Cyanobenzoic Acid (CAS 619-65-8) from TCI is a rigid, linear aromatic building block carrying both carboxylic acid and nitrile functionalities in the para position. The carboxyl group is readily activated for amide coupling and esterification, while the nitrile can be converted into tetrazoles, amidines, or aminomethyl groups. Its linear geometry and polar nitrile make it a frequent choice for metal-organic framework linkers and liquid crystal research. AMI Scientific provides this reagent in 5 g and 25 g packs for laboratory-scale synthesis.
