(2E)-2-{[(4-methoxyphenyl)amino]methylidene}-3,4-dihydro-2H-1,4-benzothiazin-3-one CAS 41526-87-8 chemical structure

Description

The occurrence of (2E)-2-{[(4-methoxyphenyl)amino]methylidene}-3,4-dihydro-2H-1,4-benzothiazin-3-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2E)-2-{[(4-methoxyphenyl)amino]methylidene}-3,4-dihydro-2H-1,4-benzothiazin-3-one (CAS 41526-87-8), a certified reference material (molecular formula C16H14N2O2S, MW 298.36 g/mol) for analytical method development and quality control.

(2E)-2-{[(4-methoxyphenyl)amino]methylidene}-3,4-dihydro-2H-1,4-benzothiazin-3-one (C16H14N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
