Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Amino-1-benzyl-3-ethyl-1H,2H,3H,4H,5H,8H-pyrido[2,3-d]pyrimidine-2,4,5-trione.
7-Amino-1-benzyl-3-ethyl-1H,2H,3H,4H,5H,8H-pyrido[2,3-d]pyrimidine-2,4,5-trione (CAS 571149-80-9), molecular formula C16H16N4O3 and molecular weight 312.32 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Amino-1-benzyl-3-ethyl-1H,2H,3H,4H,5H,8H-pyrido[2,3-d]pyrimidine-2,4,5-trione (C16H16N4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 312.32 g/mol, it falls into the moderately-high-molecular-weight range. 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), 7-Amino-1-benzyl-3-ethyl-1H,2H,3H,4H,5H,8H-pyrido[2,3-d]pyrimidine-2,4,5-trione 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.
