Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 147.58 g/mol gives 3-Fluoro-5-methylpyridine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Fluoro-5-methylpyridine hydrochloride (CAS 1373223-28-9), molecular formula C6H6FNHCl and molecular weight 147.58 g/mol, is a CATO reference standard with documented purity and traceability.
3-Fluoro-5-methylpyridine hydrochloride (C6H6FNHCl) contains a nitrile group, fluorine/chlorine substitution. 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.
As a certified reference material (CRM), 3-Fluoro-5-methylpyridine hydrochloride 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.
