3-{[(3-chlorophenyl)methyl]sulfanyl}-4H-1lambda6,4-benzothiazine-1,1-dione CAS 477868-91-0

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.

3-{[(3-chlorophenyl)methyl]sulfanyl}-4H-1lambda6,4-benzothiazine-1,1-dione (CAS 477868-91-0), molecular formula C15H12ClNO2S2 and molecular weight 337.84 g/mol, is a CATO reference standard with documented purity and traceability.

3-{[(3-chlorophenyl)methyl]sulfanyl}-4H-1lambda6,4-benzothiazine-1,1-dione (C15H12ClNO2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3-{[(3-chlorophenyl)methyl]sulfanyl}-4H-1lambda6,4-benzothiazine-1,1-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.
