3-(2-Methoxyethyl)-2-thioxo-2,3,6,7-tetrahydrothieno[3,2-d]pyrimidin-4(1h)-one CAS 1105190-35-9

Description

The molecular framework of 3-(2-Methoxyethyl)-2-thioxo-2,3,6,7-tetrahydrothieno[3,2-d]pyrimidin-4(1h)-one (C9H12N2O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-(2-Methoxyethyl)-2-thioxo-2,3,6,7-tetrahydrothieno[3,2-d]pyrimidin-4(1h)-one (CAS 1105190-35-9) is a high-purity analytical reference standard with the molecular formula C9H12N2O2S2 and a molecular weight of 244.33 g/mol.

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.
