Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7,8-Dihydro-5H-pyrido[1,2-a]thieno[3,2-d]pyrimidin-10(6H)-one (CAS 120079-42-7), molecular formula C10H10N2OS and molecular weight 206.26 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, 7,8-Dihydro-5H-pyrido[1,2-a]thieno[3,2-d]pyrimidin-10(6H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 7,8-Dihydro-5H-pyrido[1,2-a]thieno[3,2-d]pyrimidin-10(6H)-one 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.
