Chemical Structure
Description
3-fluoro-5-(pyrrolidin-3-yl)pyridine dihydrochloride (C9H11FN2HCl) contains a nitrogen-containing heterocyclic scaffold, 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.
3-fluoro-5-(pyrrolidin-3-yl)pyridine dihydrochloride (CAS 1909308-50-4) is a high-purity analytical reference standard with the molecular formula C9H11FN2HCl and a molecular weight of 202.66 g/mol.
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.
