2,5-Diphenyl-6H-1,3-thiazin-6-one CAS 52421-57-5

Description

The occurrence of 2,5-Diphenyl-6H-1,3-thiazin-6-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,5-Diphenyl-6H-1,3-thiazin-6-one (CAS 52421-57-5), molecular formula C16H11NOS and molecular weight 265.33 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-Diphenyl-6H-1,3-thiazin-6-one (C16H11NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
