Compared with other compounds in its class, the molecular weight of 222.71 g/mol gives n-Amyl-2-chlorobenzimidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
n-Amyl-2-chlorobenzimidazole (CAS 101953-55-3), molecular formula C12H15ClN2 and molecular weight 222.71 g/mol, is a CATO reference standard with documented purity and traceability.
n-Amyl-2-chlorobenzimidazole (C12H15ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), n-Amyl-2-chlorobenzimidazole 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.
