Chemical Structure
Description
The molecular framework of 2-(2-Bromobenzenesulfonamido)acetic acid (C8H8BrNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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.
2-(2-Bromobenzenesulfonamido)acetic acid (CAS 744243-47-8), molecular formula C8H8BrNO4S and molecular weight 294.12 g/mol, is a CATO reference standard with documented purity and traceability.
