Chemical Structure
Description
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.
(1E)-N-(3-Chlorophenyl)-1-[1-(4-chlorophenyl)-2,5-dimethyl-1H-pyrrol-3-yl]methanimine (CAS 357664-72-3), molecular formula C19H16Cl2N2 and molecular weight 343.25 g/mol, is a CATO reference standard with documented purity and traceability.
(1E)-N-(3-Chlorophenyl)-1-[1-(4-chlorophenyl)-2,5-dimethyl-1H-pyrrol-3-yl]methanimine (C19H16Cl2N2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
