Chemical Structure
Description
Based on its molecular formula C28H48N2I, 3-Benzyl-1-(9-(1-methylpyrrolidin-1-ium-1-yl)nonyl)quinuclidin-1-ium iodide contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 539.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-Benzyl-1-(9-(1-methylpyrrolidin-1-ium-1-yl)nonyl)quinuclidin-1-ium iodide (CAS 21252-33-5), molecular formula C28H48N2I and molecular weight 539.61 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
