Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(Morpholine-4-sulfonyl)-5-{[3-(trifluoromethyl)phenyl]methyl}-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxalin-4-one.
7-(Morpholine-4-sulfonyl)-5-{[3-(trifluoromethyl)phenyl]methyl}-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxalin-4-one (CAS 1042134-64-4), molecular formula C23H24F3N3O4S and molecular weight 495.51 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-(Morpholine-4-sulfonyl)-5-{[3-(trifluoromethyl)phenyl]methyl}-1H,2H,3H,3aH,4H,5H-pyrrolo[1,2-a]quinoxalin-4-one (C23H24F3N3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 495.51 g/mol, it falls into the moderately-high-molecular-weight range. 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.
