Chemical Structure
Description
4-((3-(Trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonyl chloride (C12H7ClF3NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
4-((3-(Trifluoromethyl)pyridin-2-yl)oxy)benzenesulfonyl chloride (CAS 874839-13-1) is a high-purity analytical reference standard with the molecular formula C12H7ClF3NO3S and a molecular weight of 337.70 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
