4-[(4-chlorophenyl)sulfonyl]-3-phenyl-3,4-dihydro-2H-1,4-benzoxazine CAS 338962-41-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 385.86 g/mol gives 4-[(4-chlorophenyl)sulfonyl]-3-phenyl-3,4-dihydro-2H-1,4-benzoxazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-[(4-chlorophenyl)sulfonyl]-3-phenyl-3,4-dihydro-2H-1,4-benzoxazine (CAS 338962-41-7), a certified reference material (molecular formula C20H16ClNO3S, MW 385.86 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 4-[(4-chlorophenyl)sulfonyl]-3-phenyl-3,4-dihydro-2H-1,4-benzoxazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 385.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
