4-Oxo-N-(2-(pyrimidin-5-yl)ethyl)-4H-chromene-2-carboxamide CAS 2034445-76-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Oxo-N-(2-(pyrimidin-5-yl)ethyl)-4H-chromene-2-carboxamide.

4-Oxo-N-(2-(pyrimidin-5-yl)ethyl)-4H-chromene-2-carboxamide (CAS 2034445-76-4), molecular formula C16H13N3O3 and molecular weight 295.29 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Oxo-N-(2-(pyrimidin-5-yl)ethyl)-4H-chromene-2-carboxamide (C16H13N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 295.29 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).

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.
