Chemical Structure

Ethyl 5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]-pyrimidine-6-carboxylate CAS 17417-67-3 chemical structure

Description

The occurrence of Ethyl 5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]-pyrimidine-6-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.

CATO supplies Ethyl 5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]-pyrimidine-6-carboxylate (CAS 17417-67-3), a certified reference material (molecular formula C10H10N2O3S, MW 238.26 g/mol) for analytical method development and quality control.

Structurally, Ethyl 5-methyl-4-oxo-3,4-dihydrothieno[2,3-d]-pyrimidine-6-carboxylate (C10H10N2O3S) 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 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 238.26 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
