Compared with other compounds in its class, the molecular weight of 370.66 g/mol gives Robenidine Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Robenidine Hydrochloride (CAS 25875-50-7), molecular formula C15H13Cl2N5HCl and molecular weight 370.66 g/mol, is a CATO reference standard with documented purity and traceability.
Robenidine Hydrochloride (C15H13Cl2N5HCl) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
