Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-7-(3-fluorophenyl)thieno[3,2-d]pyrimidin-4(1H)-one.
CATO supplies 2-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-7-(3-fluorophenyl)thieno[3,2-d]pyrimidin-4(1H)-one (CAS 1251599-14-0), a certified reference material (molecular formula C23H20ClFN4OS, MW 454.95 g/mol) for analytical method development and quality control.
2-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-7-(3-fluorophenyl)thieno[3,2-d]pyrimidin-4(1H)-one (C23H20ClFN4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)-7-(3-fluorophenyl)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.
