7-(2-Chlorophenyl)-2-(4-phenylpiperazin-1-yl)thieno[3,2-d]pyrimidin-4(1H)-one CAS 1242871-68-6

Description

7-(2-Chlorophenyl)-2-(4-phenylpiperazin-1-yl)thieno[3,2-d]pyrimidin-4(1H)-one (CAS 1242871-68-6) is a high-purity analytical reference standard with the molecular formula C22H19ClN4OS and a molecular weight of 422.93 g/mol.

The molecular framework of 7-(2-Chlorophenyl)-2-(4-phenylpiperazin-1-yl)thieno[3,2-d]pyrimidin-4(1H)-one (C22H19ClN4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
