4-(4-Methoxyphenyl)-4H-benzo[b][1,4]thiazine-2-carbonitrile 1,1-dioxide CAS 1207008-94-3

Description

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.

4-(4-Methoxyphenyl)-4H-benzo[b][1,4]thiazine-2-carbonitrile 1,1-dioxide (CAS 1207008-94-3), molecular formula C16H12N2O3S and molecular weight 312.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(4-Methoxyphenyl)-4H-benzo[b][1,4]thiazine-2-carbonitrile 1,1-dioxide (C16H12N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-(4-Methoxyphenyl)-4H-benzo[b][1,4]thiazine-2-carbonitrile 1,1-dioxide 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.
