4-(tert-Butyl)-N-(5-hydroxy-4-methyl-2-(2-oxo-3-phenylindolin-3-yl)phenyl)benzenesulfonamide CAS 783324-18-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(tert-Butyl)-N-(5-hydroxy-4-methyl-2-(2-oxo-3-phenylindolin-3-yl)phenyl)benzenesulfonamide.

4-(tert-Butyl)-N-(5-hydroxy-4-methyl-2-(2-oxo-3-phenylindolin-3-yl)phenyl)benzenesulfonamide (CAS 783324-18-5) is a high-purity analytical reference standard with the molecular formula C31H30N2O4S and a molecular weight of 526.65 g/mol.

Based on its molecular formula C31H30N2O4S, 4-(tert-Butyl)-N-(5-hydroxy-4-methyl-2-(2-oxo-3-phenylindolin-3-yl)phenyl)benzenesulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 526.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
