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.
CATO supplies (1E)-N-(4-Fluoro-3-methylphenyl)-1-(2-fluorophenyl)methanimine (CAS 329699-40-3), a certified reference material (molecular formula C14H11F2N, MW 231.24 g/mol) for analytical method development and quality control.
The molecular framework of (1E)-N-(4-Fluoro-3-methylphenyl)-1-(2-fluorophenyl)methanimine (C14H11F2N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
