Chemical Structure
Description
2-tert-Butoxycarbonylamino-3-(tert-butyl-dimethyl-silanyloxy)-3-(3-methoxy-phenyl)-propionic acidd (C21H35NO6Si) contains a steroid core, an amide 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
