CATO supplies [S(R)]-N-[(S)-[3,5-Di-tert-butyl-4-methoxyphenyl][5-(diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl]methyl]-2-methyl-2-propanesulfinamide (CAS 2565792-28-9), a certified reference material (molecular formula C47H56NO3PS, MW 745.99 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage, [S(R)]-N-[(S)-[3,5-Di-tert-butyl-4-methoxyphenyl][5-(diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl]methyl]-2-methyl-2-propanesulfinamide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 745.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), [S(R)]-N-[(S)-[3,5-Di-tert-butyl-4-methoxyphenyl][5-(diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl]methyl]-2-methyl-2-propanesulfinamide 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.
