Description

2,6-Bis[(3aR,8aS)-(+)-8H-indeno[1,2-d]oxazolin-2-yl)pyridine 357209-32-6 (3AR,3'AR,8AS,8'AS)-2,2'-(2,6-PYRIDINEDIYL)BIS3A,8A-DIHYDRO-8H-INDENO[1,2-D]OXAZOLE;(3AR,8AS)-IN-PYBOX;2,6-BIS[(3AR,8AS)-(+)-8H-INDENO[1,2-D]OXAZOLIN-2-YL]PYRIDINE;2,6-Bis[(3aR,8aS)-(+)-8H-indeno[1,2-d]oxazolin-2-yl)pyridine SC11771 (C25H37N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
