Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Benzyl-1-dodecyl-2-methyl-1H-imidazol-3-ium chloride (CAS 21054-72-8), molecular formula C23H37N2Cl and molecular weight 377.01 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C23H37N2Cl, 3-Benzyl-1-dodecyl-2-methyl-1H-imidazol-3-ium chloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 377.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
As a certified reference material (CRM), 3-Benzyl-1-dodecyl-2-methyl-1H-imidazol-3-ium chloride 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.
