Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Chloro-4-methanesulfonyl-N-{4-[3-(trifluoromethyl)benzenesulfonyl]phenyl}benzamide (CAS 339105-03-2), a certified reference material (molecular formula C21H15ClF3NO5S2, MW 517.93 g/mol) for analytical method development and quality control.
2-Chloro-4-methanesulfonyl-N-{4-[3-(trifluoromethyl)benzenesulfonyl]phenyl}benzamide (C21H15ClF3NO5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2-Chloro-4-methanesulfonyl-N-{4-[3-(trifluoromethyl)benzenesulfonyl]phenyl}benzamide 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.
