5-ethyl-6-methyl-2-(2-morpholin-4-yl-2-oxoethyl)thieno[2,3-d]pyrimidin-4(3H)-one CAS 735288-62-7

Description

The occurrence of 5-ethyl-6-methyl-2-(2-morpholin-4-yl-2-oxoethyl)thieno[2,3-d]pyrimidin-4(3H)-one 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.

5-ethyl-6-methyl-2-(2-morpholin-4-yl-2-oxoethyl)thieno[2,3-d]pyrimidin-4(3H)-one (CAS 735288-62-7), molecular formula C15H19N3O3S and molecular weight 321.39 g/mol, is a CATO reference standard with documented purity and traceability.

5-ethyl-6-methyl-2-(2-morpholin-4-yl-2-oxoethyl)thieno[2,3-d]pyrimidin-4(3H)-one (C15H19N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
