4-Chloro-2-(perfluoroethyl)pyridine (CAS 1816283-20-1), molecular formula C7H3ClF5N and molecular weight 231.55 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Chloro-2-(perfluoroethyl)pyridine (C7H3ClF5N) contains a nitrile group, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 231.55 g/mol, it falls into the medium-molecular-weight range. 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.
