TCI C1196 4-Carboxymethyl-6,7-methylenedioxycoumarin, CAS 97744-77-9, is a coumarin-based heterocyclic building block bearing a pendant carboxylic acid group. The carboxyl handle allows straightforward conjugation to amines, alcohols, peptides, and other biomolecules, turning the coumarin core into a covalently attached fluorophore. Researchers commonly use such reagents for fluorescent labelling, pre-column derivatisation in HPLC analysis, and the design of fluorescent probes and sensors. AMI Scientific supplies 200 mg and 1 g pack sizes for research use; store the material protected from light and moisture as indicated by the manufacturer.
