Retinoyl fluoride can be mixed with commercially available glucuronic acid. The reaction is carried out in acetone/water to facilitate the solubility of the water-insoluble retinoyl fluoride and the water-soluble glucuronic acid. The reaction takes place in slightly alkaline pH and hence sodium bicarbonate is used in the reaction mixture. Stirring the mixture at room temperature for 20-24 hours followed by acidification of the solution and extraction with ethyl acetate yields retinoyl glucuronide as the major product. Pure all-trans retinoyl β-glucuronide can be obtained by a combination of column and high-performance liquid chromatography (HPLC).
