Chemical Structure
Description
As a certified reference material (CRM), 2-(4-Oxo-4H-benzo[e][1,3]thiazin-2-yl)-N-(3-(trifluoromethyl)phenyl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2-(4-Oxo-4H-benzo[e][1,3]thiazin-2-yl)-N-(3-(trifluoromethyl)phenyl)acetamide (CAS 338975-34-1), a certified reference material (molecular formula C17H11F3N2O2S, MW 364.34 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-Oxo-4H-benzo[e][1,3]thiazin-2-yl)-N-(3-(trifluoromethyl)phenyl)acetamide (C17H11F3N2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
