3-Oxo-4-phenyl-3,4-dihydro-2H-benzo[b][1,4]thiazine-7-carbonitrile CAS 1400566-20-2 chemical structure

Description

The occurrence of 3-Oxo-4-phenyl-3,4-dihydro-2H-benzo[b][1,4]thiazine-7-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Oxo-4-phenyl-3,4-dihydro-2H-benzo[b][1,4]thiazine-7-carbonitrile (CAS 1400566-20-2), a certified reference material (molecular formula C15H10N2OS, MW 266.32 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H10N2OS, 3-Oxo-4-phenyl-3,4-dihydro-2H-benzo[b][1,4]thiazine-7-carbonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 266.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
