Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(1-Acetyl-1H-indol-3-yl)-4-hydroxy-2H-chromen-2-one.
CATO supplies 3-(1-Acetyl-1H-indol-3-yl)-4-hydroxy-2H-chromen-2-one (CAS 63291-66-7), a certified reference material (molecular formula C19H13NO4, MW 319.31 g/mol) for analytical method development and quality control.
3-(1-Acetyl-1H-indol-3-yl)-4-hydroxy-2H-chromen-2-one (C19H13NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
