As a certified reference material (CRM), S-(4,6-Diaminopyrimidin-2-yl) benzothioate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
S-(4,6-Diaminopyrimidin-2-yl) benzothioate (CAS 65349-39-5), molecular formula C11H10N4OS and molecular weight 246.29 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, S-(4,6-Diaminopyrimidin-2-yl) benzothioate is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 246.29 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.
