3,5,6,7-Tetrahydro-2-methyl-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidine-4-thione CAS 307342-23-0

Description

Compared with other compounds in its class, the molecular weight of 222.33 g/mol gives 3,5,6,7-Tetrahydro-2-methyl-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidine-4-thione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5,6,7-Tetrahydro-2-methyl-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidine-4-thione (CAS 307342-23-0) is a high-purity analytical reference standard with the molecular formula C10H10N2S2 and a molecular weight of 222.33 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3,5,6,7-Tetrahydro-2-methyl-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidine-4-thione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
