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-(Cyano(2,4-dichlorophenyl)methyl)-6-fluorobenzonitrile (CAS 338965-45-0) is a high-purity analytical reference standard with the molecular formula C15H7Cl2FN2 and a molecular weight of 305.13 g/mol.
The molecular framework of 2-(Cyano(2,4-dichlorophenyl)methyl)-6-fluorobenzonitrile (C15H7Cl2FN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine 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.
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.
