3-amino-5-phenyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one CAS 571158-77-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-amino-5-phenyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one.

3-amino-5-phenyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one (CAS 571158-77-5) is a high-purity analytical reference standard with the molecular formula C12H21N3OS2 and a molecular weight of 287.44 g/mol.

Based on its molecular formula C12H21N3OS2, 3-amino-5-phenyl-2-sulfanyl-3H,4H-thieno[2,3-d]pyrimidin-4-one contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 287.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
