The molecular framework of N-nitroso-colistin b hydrogen methanesulfonate-4 (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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
N-nitroso-colistin b hydrogen methanesulfonate-4 (CAS CATO-C4X-225554) is a high-purity analytical reference standard with the molecular formula C57H107N17O29S5 and a molecular weight of 1654.88 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
