2-Chloro-5-(chlorodifluoromethyl)pyridine (CAS 71701-84-3) is a high-purity analytical reference standard with the molecular formula C6H3Cl2F2N and a molecular weight of 198.00 g/mol.
2-Chloro-5-(chlorodifluoromethyl)pyridine (C6H3Cl2F2N) contains a nitrile group, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
