4-Chloro-3-fluoropyridine Hydrochloride (CAS 119229-74-2), molecular formula C5H3ClFNHCl and molecular weight 167.99 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-3-fluoropyridine Hydrochloride (C5H3ClFNHCl) contains 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
