Ethyl 3-methyl-4h-benzo[b][1,4]thiazine-2-carboxylate (CAS 7625-01-6) is a high-purity analytical reference standard with the molecular formula C12H13NO2S and a molecular weight of 235.30 g/mol.
The molecular framework of Ethyl 3-methyl-4h-benzo[b][1,4]thiazine-2-carboxylate (C12H13NO2S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
