CATO supplies 3-(4-Chlorophenyl)-2-((2-(2-chlorophenyl)-2-oxoethyl)thio)-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3H)-one (CAS 573940-83-7), a certified reference material (molecular formula C24H18Cl2N2O2S2, MW 501.45 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-Chlorophenyl)-2-((2-(2-chlorophenyl)-2-oxoethyl)thio)-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3H)-one (C24H18Cl2N2O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
As a certified reference material (CRM), 3-(4-Chlorophenyl)-2-((2-(2-chlorophenyl)-2-oxoethyl)thio)-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3H)-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.
