Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Fluoro-5-(piperidin-3-yl)pyridine hydrochloride (CAS 2138576-56-2), molecular formula C10H13FN2HCl and molecular weight 216.68 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-5-(piperidin-3-yl)pyridine hydrochloride (C10H13FN2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-Fluoro-5-(piperidin-3-yl)pyridine 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.
