Chemical Structure
Description
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.
CATO supplies 3-(((2-Fluorophenyl)amino)methylene)-1-(4-methylbenzyl)-1H-benzo[c][1,2]thiazin-4(3H)-one 2,2-dioxide (CAS 893310-53-7), a certified reference material (molecular formula C23H19FN2O3S, MW 422.47 g/mol) for analytical method development and quality control.
3-(((2-Fluorophenyl)amino)methylene)-1-(4-methylbenzyl)-1H-benzo[c][1,2]thiazin-4(3H)-one 2,2-dioxide (C23H19FN2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
