Chemical Properties

White crystals or crystalline powder

Uses

O-Methylisourea Hemisulfate was used as a reagent in the preparation of (D,L)-arginine methyl ester analogs which display antiarrhythmic actiivity. It was also used in the synthesis of ethyl [6-methyl-2-methoxy-3-(substituted phenylethanone)-4-(substituted phenyl)]-1,2,3,4-tetrahydropyrimidine-5-carboxylates which display antimicrobial activity towards mycobacterium tuberculosis, staphylococcus aureus and bacillus subtilis at varying conentration ranges.
