CATO supplies 2-[[4-[[[4-(tert-Butyl)phenyl]sulfonyl]imino]-1-oxo-1,4-dihydro-2-naphthyl]thio]acetic Acid (CAS 881487-77-0), a certified reference material (molecular formula C22H21NO5S2, MW 443.54 g/mol) for analytical method development and quality control.
2-[[4-[[[4-(tert-Butyl)phenyl]sulfonyl]imino]-1-oxo-1,4-dihydro-2-naphthyl]thio]acetic Acid (C22H21NO5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; 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).
As a certified reference material (CRM), 2-[[4-[[[4-(tert-Butyl)phenyl]sulfonyl]imino]-1-oxo-1,4-dihydro-2-naphthyl]thio]acetic Acid 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.
