(+)-Potassium Ds-threo-isocitrate monobasic (1R,2S)-1-Hydroxy-1,2,3-propanetricarboxylic acid monopotassium salt 20226-99-7 Ds-(+)-threo-Isocitric acid monopotassium salt (CAS 20226-99-7), molecular formula C6H7O7K and molecular weight 230.21 g/mol, is a CATO reference standard with documented purity and traceability.

(+)-Potassium Ds-threo-isocitrate monobasic (1R,2S)-1-Hydroxy-1,2,3-propanetricarboxylic acid monopotassium salt 20226-99-7 Ds-(+)-threo-Isocitric acid monopotassium salt (C6H7O7K) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).
