Chemical Structure

5-methyl-6-phenyl-2-sulfanylidene-1,2,3,4-tetrahydropyrimidin-4-one CAS 109942-16-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

5-methyl-6-phenyl-2-sulfanylidene-1,2,3,4-tetrahydropyrimidin-4-one (CAS 109942-16-7), molecular formula C11H12N2OS and molecular weight 220.29 g/mol, is a CATO reference standard with documented purity and traceability.

5-methyl-6-phenyl-2-sulfanylidene-1,2,3,4-tetrahydropyrimidin-4-one (C11H12N2OS) 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).

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.
