Chemical Structure
Description
The molecular framework of 4,5-dimethyl-1H-imidazole-2-sulfonyl fluoride hydrochloride (C5H7FN2O2SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
4,5-dimethyl-1H-imidazole-2-sulfonyl fluoride hydrochloride (CAS 2044902-12-5), molecular formula C5H7FN2O2SHCl and molecular weight 214.64 g/mol, is a CATO reference standard with documented purity and traceability.
