3-Methyl-1,3-thiazinane-2,4-dione CAS 1003-92-5

Description

The occurrence of 3-Methyl-1,3-thiazinane-2,4-dione is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Methyl-1,3-thiazinane-2,4-dione (CAS 1003-92-5), molecular formula C5H7NO2S and molecular weight 145.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Methyl-1,3-thiazinane-2,4-dione (C5H7NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 3-Methyl-1,3-thiazinane-2,4-dione 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.
