4-[5-(4-Fluoropyrrolidin-2-yl)-1,2,4-oxadiazol-3-yl]pyridine dihydrochloride (CAS 2034460-57-4), molecular formula C11H11FN4OHCl and molecular weight 270.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-[5-(4-Fluoropyrrolidin-2-yl)-1,2,4-oxadiazol-3-yl]pyridine dihydrochloride (C11H11FN4OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
