Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1654.88 g/mol gives N-nitroso-colistin b hydrogen methanesulfonate-2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-nitroso-colistin b hydrogen methanesulfonate-2 (CAS CATO-C4X-225552), molecular formula C57H107N17O29S5 and molecular weight 1654.88 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-nitroso-colistin b hydrogen methanesulfonate-2 (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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-nitroso-colistin b hydrogen methanesulfonate-2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
