Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium chloride, mixt. with cesium fluoride (CAS 1648825-53-9), molecular formula C27H36ClN2CsFCl and molecular weight 611.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium chloride, mixt. with cesium fluoride (C27H36ClN2CsFCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 611.41 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
