Chemical Structure

(S)-N-(5-(tert-Butyl)-4-((4-hydroxy-6-(4-hydroxyphenethyl)-6-isopropyl-2-oxo-5,6-dihydro-2H-pyran-3-yl)thio)-2-methylphenyl)-5-(trifluoromethyl)pyridine-2-sulfonamide CAS 263842-59-7 chemical structure

Description

(S)-N-(5-(tert-Butyl)-4-((4-hydroxy-6-(4-hydroxyphenethyl)-6-isopropyl-2-oxo-5,6-dihydro-2H-pyran-3-yl)thio)-2-methylphenyl)-5-(trifluoromethyl)pyridine-2-sulfonamide (C33H37F3N2O6S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
