Chemical Structure
Description
The occurrence of 6,7-Methylenedioxy-4-isocyanatomethylcoumarin [for HPLC Labeling] is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6,7-Methylenedioxy-4-isocyanatomethylcoumarin [for HPLC Labeling] (CAS 97744-89-3), a certified reference material (molecular formula C12H7NO5, MW 245.19 g/mol) for analytical method development and quality control.
6,7-Methylenedioxy-4-isocyanatomethylcoumarin [for HPLC Labeling] (C12H7NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
