Chemical Structure
Description
As a certified reference material (CRM), 4-{6-[(4-chlorobenzenesulfinyl)methyl]-2-phenylpyrimidin-4-yl}morpholine 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.
4-{6-[(4-chlorobenzenesulfinyl)methyl]-2-phenylpyrimidin-4-yl}morpholine (CAS 306980-67-6), molecular formula C21H20ClN3O2S and molecular weight 413.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-{6-[(4-chlorobenzenesulfinyl)methyl]-2-phenylpyrimidin-4-yl}morpholine (C21H20ClN3O2S) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
