Description
As a certified reference material (CRM), N-nitroso-colistin b hydrogen methanesulfonate-3 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.
N-nitroso-colistin b hydrogen methanesulfonate-3 (CAS CATO-C4X-225553) is a high-purity analytical reference standard with the molecular formula C57H107N17O29S5 and a molecular weight of 1654.88 g/mol.
Structurally, N-nitroso-colistin b hydrogen methanesulfonate-3 (C57H107N17O29S5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 1654.88 g/mol, it falls into the high-molecular-weight range. 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).
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.
