3-(2-Oxo-2-(thiophen-2-yl)ethyl)thieno[2,3-d]pyrimidin-4(3H)-one CAS 878913-79-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Oxo-2-(thiophen-2-yl)ethyl)thieno[2,3-d]pyrimidin-4(3H)-one.

3-(2-Oxo-2-(thiophen-2-yl)ethyl)thieno[2,3-d]pyrimidin-4(3H)-one (CAS 878913-79-2) is a high-purity analytical reference standard with the molecular formula C12H8N2O2S2 and a molecular weight of 276.33 g/mol.

Structurally, 3-(2-Oxo-2-(thiophen-2-yl)ethyl)thieno[2,3-d]pyrimidin-4(3H)-one (C12H8N2O2S2) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 276.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
