2,3,4-Tri-O-acetyl-a-D-glucuronic acid methyl ester is a hydroxylated glucuronic acid that is found in the structural skeleton of many organisms. It has been shown to have isosteric properties and it can be used as a transport agent for xenobiotics. 2,3,4-Tri-O-acetyl-a-D-glucuronic acid methyl ester is metabolized by alcohols and hydrolysis to form adducts with nitrosoamines. These adducts are excreted from the body through urine.
