TCI C1104 Comanic Acid (CAS 499-05-8) is a heterocyclic building block featuring a pyranone ring bearing a carboxylic acid group. The conjugated oxygen-containing ring offers reactivity patterns distinct from ordinary aromatics, including conversion to pyridinone systems on treatment with amines. The carboxyl group provides an additional handle for amidation, esterification and metal coordination studies. AMI Scientific offers this TCI product in 1 g, 5 g and 25 g packs to suit both exploratory and routine synthetic work.
