Ethyl 4-((2-ethoxy-2-oxoethyl)thio)-6-methyl-2-oxo-1,2-dihydropyrimidine-5-carboxylate CAS 900002-07-5 chemical structure

Description

The occurrence of Ethyl 4-((2-ethoxy-2-oxoethyl)thio)-6-methyl-2-oxo-1,2-dihydropyrimidine-5-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 4-((2-ethoxy-2-oxoethyl)thio)-6-methyl-2-oxo-1,2-dihydropyrimidine-5-carboxylate (CAS 900002-07-5) is a high-purity analytical reference standard with the molecular formula C12H16N2O5S and a molecular weight of 300.33 g/mol.

Structurally, Ethyl 4-((2-ethoxy-2-oxoethyl)thio)-6-methyl-2-oxo-1,2-dihydropyrimidine-5-carboxylate (C12H16N2O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 300.33 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
