2-Carboxybenzaldehyde Chemical Properties,Uses,Production

Chemical Properties

white to slightly beige crystalline powder

Uses

2-Carboxybenzaldehyde is a carboxylated derivative of benzaldehyde which is readily converted to 2-hydroxymethyl benzoic acid by CBA dehydrogenase. 2-Carboxybenzaldehyde is a metabolite of ampicillin phthalidyl ester. It has been used to synthesize a series of N-substituted isoindolinones by reductive C-N coupling and intramolecular amidation with amines.

Definition

ChEBI: An aldehydic acid which consists of benzoic acid substituted by a formyl group at position 2.
