H-Asp(OBzl)-OBzl · p-tosylate (CAS 2886-33-1), molecular formula C18H19NO4C7H8O3S and molecular weight 485.55 g/mol, is a CATO reference standard with documented purity and traceability.
H-Asp(OBzl)-OBzl · p-tosylate (C18H19NO4C7H8O3S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
