4-(4-Chlorophenyl)-3-oxo-3,4-dihydro-2H-benzo[b][1,4]thiazine-7-carbonitrile CAS 1400566-24-6

Description

The occurrence of 4-(4-Chlorophenyl)-3-oxo-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, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(4-Chlorophenyl)-3-oxo-3,4-dihydro-2H-benzo[b][1,4]thiazine-7-carbonitrile (CAS 1400566-24-6), a certified reference material (molecular formula C15H9ClN2OS, MW 300.76 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H9ClN2OS, 4-(4-Chlorophenyl)-3-oxo-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, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.76 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
