Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 137.58 g/mol gives 4-Fluoro-1,2,3,6-tetrahydropyridine;hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Fluoro-1,2,3,6-tetrahydropyridine;hydrochloride (CAS 281652-11-7), molecular formula C5H8FNHCl and molecular weight 137.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Fluoro-1,2,3,6-tetrahydropyridine;hydrochloride (C5H8FNHCl) is characterized by 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
