Chemical Structure
Description
The molecular framework of tert-Butyl(7S,9S)-7-ethynyl-9-methyl-1,4-dioxa-8-azaspiro[4.5]decane-8-carboxylate (C15H23NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
