Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Pyridin-2-yl-2-thioxo-2,3-dihydropyrimidin-4(1{H})-one.
6-Pyridin-2-yl-2-thioxo-2,3-dihydropyrimidin-4(1{H})-one (CAS 64670-16-2), molecular formula C9H7N3OS and molecular weight 205.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 6-Pyridin-2-yl-2-thioxo-2,3-dihydropyrimidin-4(1{H})-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 205.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
