Chemical Structure
Description
The occurrence of (R)-Ketoprofen β-D-glucuronide is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-Ketoprofen β-D-glucuronide (CAS 140148-25-0) is a high-purity analytical reference standard with the molecular formula C22H22O9 and a molecular weight of 430.40 g/mol.
(R)-Ketoprofen β-D-glucuronide (C22H22O9) contains a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
