Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-Phenyl-2-thioxo-2,3-dihydropteridin-4(1H)-one (CAS 705287-02-1), molecular formula C12H8N4OS and molecular weight 256.28 g/mol, is a CATO reference standard with documented purity and traceability.
7-Phenyl-2-thioxo-2,3-dihydropteridin-4(1H)-one (C12H8N4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
