Chemical Structure
Description
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.
CATO supplies 3-Cyclopropyl-5-(4-fluoropyrrolidin-2-yl)-1,2,4-oxadiazole hydrochloride (CAS 2097932-65-3), a certified reference material (molecular formula C9H12FN3OHCl, MW 233.67 g/mol) for analytical method development and quality control.
3-Cyclopropyl-5-(4-fluoropyrrolidin-2-yl)-1,2,4-oxadiazole hydrochloride (C9H12FN3OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.
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.
