CATO supplies N-(2-Cyano-3-methylbutan-2-yl)-2-((5,6-dimethylthieno[2,3-d]pyrimidin-4-yl)thio)acetamide (CAS 745067-15-6), a certified reference material (molecular formula C16H20N4OS2, MW 348.49 g/mol) for analytical method development and quality control.
The molecular framework of N-(2-Cyano-3-methylbutan-2-yl)-2-((5,6-dimethylthieno[2,3-d]pyrimidin-4-yl)thio)acetamide (C16H20N4OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), N-(2-Cyano-3-methylbutan-2-yl)-2-((5,6-dimethylthieno[2,3-d]pyrimidin-4-yl)thio)acetamide 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.
