Chemical Structure
Description
The molecular framework of N-nitroso-colistin b hydrogen methanesulfonate-5 (C57H107N17O29S5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
N-nitroso-colistin b hydrogen methanesulfonate-5 (CAS CATO-C4X-225555), molecular formula C57H107N17O29S5 and molecular weight 1654.88 g/mol, is a CATO reference standard with documented purity and traceability.
