3-Cyclopentyl-2-mercapto-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3h)-one CAS 173727-47-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 306.45 g/mol gives 3-Cyclopentyl-2-mercapto-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3h)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Cyclopentyl-2-mercapto-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3h)-one (CAS 173727-47-4) is a high-purity analytical reference standard with the molecular formula C15H18N2OS2 and a molecular weight of 306.45 g/mol.

The molecular framework of 3-Cyclopentyl-2-mercapto-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3h)-one (C15H18N2OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
