Chemical Structure
Description
The molecular framework of 2-Fluoro-5-methylpyridine (C6H6FN) is characterized by a nitrile group, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
CATO supplies 2-Fluoro-5-methylpyridine (CAS 2369-19-9), a certified reference material (molecular formula C6H6FN, MW 111.12 g/mol) for analytical method development and quality control.
