3-(4-Fluorophenyl)-6-methyl-2-thioxo-2,3,6,7-tetrahydrothieno[3,2-d]pyrimidin-4(1H)-one CAS 1105190-55-3

Description

The occurrence of 3-(4-Fluorophenyl)-6-methyl-2-thioxo-2,3,6,7-tetrahydrothieno[3,2-d]pyrimidin-4(1H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Fluorophenyl)-6-methyl-2-thioxo-2,3,6,7-tetrahydrothieno[3,2-d]pyrimidin-4(1H)-one (CAS 1105190-55-3) is a high-purity analytical reference standard with the molecular formula C13H11FN2OS2 and a molecular weight of 294.37 g/mol.

Structurally, 3-(4-Fluorophenyl)-6-methyl-2-thioxo-2,3,6,7-tetrahydrothieno[3,2-d]pyrimidin-4(1H)-one (C13H11FN2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 294.37 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.
