Chemical Structure
Description
2-(4-Oxo-6-propylthieno[2,3-d]pyrimidin-3(4h)-yl)propanehydrazide (CAS 832740-08-6), molecular formula C12H16N4O2S and molecular weight 280.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(4-Oxo-6-propylthieno[2,3-d]pyrimidin-3(4h)-yl)propanehydrazide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.35 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.
As a certified reference material (CRM), 2-(4-Oxo-6-propylthieno[2,3-d]pyrimidin-3(4h)-yl)propanehydrazide 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.
