Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5,6-Dimethyl-4-(piperazin-1-yl)thieno[2,3-d]pyrimidine (CAS 683274-62-6), molecular formula C12H16N4S and molecular weight 248.35 g/mol, is a CATO reference standard with documented purity and traceability.
5,6-Dimethyl-4-(piperazin-1-yl)thieno[2,3-d]pyrimidine (C12H16N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 5,6-Dimethyl-4-(piperazin-1-yl)thieno[2,3-d]pyrimidine 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.
