5-Chloro-2-fluoro-4-methylpyridine 5-chloro-2-fluoro-4-picoline 884494-88-6 (CAS 884494-88-6) is a high-purity analytical reference standard with the molecular formula C6H5ClFN and a molecular weight of 145.56 g/mol.
5-Chloro-2-fluoro-4-methylpyridine 5-chloro-2-fluoro-4-picoline 884494-88-6 (C6H5ClFN) contains a nitrile group, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
