Compared with other compounds in its class, the molecular weight of 496.01 g/mol gives Isometamidium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Isometamidium chloride (CAS 34301-55-8), molecular formula C28H26N7Cl and molecular weight 496.01 g/mol, is a CATO reference standard with documented purity and traceability.
Isometamidium chloride (C28H26N7Cl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
