Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9-Hydroxy-4-phenylpyrrolo[3,4-c]carbazole-1,3(2H,6H)-dione hydrate.
CATO supplies 9-Hydroxy-4-phenylpyrrolo[3,4-c]carbazole-1,3(2H,6H)-dione hydrate (CAS 1177150-89-8), a certified reference material (molecular formula C20H12N2O3H2O, MW 346.34 g/mol) for analytical method development and quality control.
9-Hydroxy-4-phenylpyrrolo[3,4-c]carbazole-1,3(2H,6H)-dione hydrate (C20H12N2O3H2O) contains a flavonoid core, 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 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.
