Description

5-((Methyl(phenyl)amino)methyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 89665-78-1), molecular formula C12H13N3OS and molecular weight 247.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-((Methyl(phenyl)amino)methyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (C12H13N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 247.32 g/mol, it falls into the medium-molecular-weight range. 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.
