Chemical Structure
Description
(1E)-N-(4-Bromo-3-methylphenyl)-1-[4-(1H-imidazol-1-yl)phenyl]methanimine (CAS 866157-64-4), molecular formula C17H14BrN3 and molecular weight 340.22 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H14BrN3, (1E)-N-(4-Bromo-3-methylphenyl)-1-[4-(1H-imidazol-1-yl)phenyl]methanimine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
