4-({4-oxo-2-sulfanylidene-1H,2H,3H,4H-thieno[3,2-d]pyrimidin-3-yl}methyl)benzoic acid CAS 728039-55-2

Description

The occurrence of 4-({4-oxo-2-sulfanylidene-1H,2H,3H,4H-thieno[3,2-d]pyrimidin-3-yl}methyl)benzoic acid 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.

4-({4-oxo-2-sulfanylidene-1H,2H,3H,4H-thieno[3,2-d]pyrimidin-3-yl}methyl)benzoic acid (CAS 728039-55-2) is a high-purity analytical reference standard with the molecular formula C14H10N2O3S2 and a molecular weight of 318.37 g/mol.

Based on its molecular formula C14H10N2O3S2, 4-({4-oxo-2-sulfanylidene-1H,2H,3H,4H-thieno[3,2-d]pyrimidin-3-yl}methyl)benzoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 318.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
