6-Hydroxy-5-nitro-2-(propylthio)-4(3H)-pyrimidinone

It is mainly used to prepare the subsequent key intermediate, 4,6-dichloro-5-nitro-2-(propylthio)pyrimidine, via chlorination. 6-Hydroxy-5-nitro-2-(propylthio)-4(3H)-pyrimidinone (also known as 5-nitro-2-(propylthio)pyrimidine-4,6-diol or its tautomer) is a critical early-stage intermediate in the industrial synthesis of the anti-platelet drug Ticagrelor.
