Chemical Structure
Description
Structurally, 3-Benzyl-1-cyclopropyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (C15H13N3O2) 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 267.28 g/mol, it falls into the medium-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).
3-Benzyl-1-cyclopropyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (CAS 519056-48-5), molecular formula C15H13N3O2 and molecular weight 267.28 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
