Chemical Structure
Description
The molecular framework of 6,6-Dioxo-6-thia-1-azaspiro[3.3]heptane hemioxalate (C5H9NO2SC2H2O4) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
