Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.42 g/mol gives 2,3,5-Trichloro-4,6-difluoropyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,3,5-Trichloro-4,6-difluoropyridine (CAS 34415-31-1), a certified reference material (molecular formula C5Cl3F2N, MW 218.42 g/mol) for analytical method development and quality control.
The molecular framework of 2,3,5-Trichloro-4,6-difluoropyridine (C5Cl3F2N) is characterized by a nitrile group, fluorine/chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 2,3,5-Trichloro-4,6-difluoropyridine 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.
