Bilirubin monoglucuronide is a conjugated bilirubin metabolite formed by glucuronidation of bilirubin. It is mainly used as a biochemical reference standard, analytical standard, research reagent in clinical chemistry, liver metabolism studies, bilirubin transport research, and enzymatic studies involving UDP-glucuronosyltransferase pathways.
