The occurrence of 4-Fluoro-3,5-dimethylpyridine is closely related to a nitrile group, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Fluoro-3,5-dimethylpyridine (CAS 37669-66-2), a certified reference material (molecular formula C7H8FN, MW 125.14 g/mol) for analytical method development and quality control.
The molecular framework of 4-Fluoro-3,5-dimethylpyridine (C7H8FN) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 4-Fluoro-3,5-dimethylpyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
