Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

3-(((4-Ethylphenyl)amino)methylene)-1-(4-methylbenzyl)-1H-benzo[c][1,2]thiazin-4(3H)-one 2,2-dioxide (CAS 893311-97-2) is a high-purity analytical reference standard with the molecular formula C25H24N2O3S and a molecular weight of 432.53 g/mol.

The molecular framework of 3-(((4-Ethylphenyl)amino)methylene)-1-(4-methylbenzyl)-1H-benzo[c][1,2]thiazin-4(3H)-one 2,2-dioxide (C25H24N2O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
