Description

CATO supplies 2-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-7-(3-chlorophenyl)thieno[3,2-d]pyrimidin-4(1H)-one (CAS 1242864-74-9), a certified reference material (molecular formula C23H20Cl2N4OS, MW 471.40 g/mol) for analytical method development and quality control.

The molecular framework of 2-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-7-(3-chlorophenyl)thieno[3,2-d]pyrimidin-4(1H)-one (C23H20Cl2N4OS) 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. 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.

As a certified reference material (CRM), 2-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-7-(3-chlorophenyl)thieno[3,2-d]pyrimidin-4(1H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
