8-Hydroxyquinoline sulphate (2:1) monopotassium salt (CAS 15077-57-3), molecular formula C9H7NOHO4SK and molecular weight 281.32 g/mol, is a CATO reference standard with documented purity and traceability.
8-Hydroxyquinoline sulphate (2:1) monopotassium salt (C9H7NOHO4SK) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
