2-Phenyl-N-((4-(thiophen-2-yl)tetrahydro-2H-pyran-4-yl)methyl)ethane-1-sulfonamide CAS 1203328-55-5 chemical structure

Description

2-Phenyl-N-((4-(thiophen-2-yl)tetrahydro-2H-pyran-4-yl)methyl)ethane-1-sulfonamide (C18H23NO3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
