4885 T3D4830 Glycoluril Glycoluril is a nitrogenous substance obtained by the reduction of allantoin. Glycoluril can be used to make Cucurbiturils. Cucurbiturils are macrocyclic molecules made of glycoluril (=C4H2N4O2=) monomers linked by methylene bridges. They have been used by chemists for various applications, including drug delivery, asymmetric synthesis, molecular switching, and dye tuning. 496-46-8 62347 C4H6N4O2 White powder.
