The kinetics and mechanism of racemization of allantoin have been examined; racemization proceeds via two independent pathways that can be separately monitored. One pathway involves proton exchange at C5 with solvent. The other pathway occurs via intramolecular attack of N8 on C4 to form a symmetric
