4-methyl cinnamic acid methyl esterCAS No.: 20754-20-5Appearance: Color white to pale yellow crystalline powderPurity:>98%Package specification:25 kg / cardboard drumStorage: Pay attention to the source of fire, especially to avoid sunlight, and store in a cool place.Usage:METHYL4-METHYLCINNAMATE is mainly used to synthesize methyl p-bromomethyl cinnamate as an upstream raw material for the antithrombotic drug Ozagrel Sodium. P-bromomethylcinnamate is brominated with N-bromosuccinimide to produce p-bromomethylcinnamate. Methyl p-bromomethylcinnamate is in ionic liquid N-n-butylpyridine tetrafluoroborate. After alkaline condensation with the imidazole in the acid salt at room temperature, the antithrombotic drug ozagrel sodium was obtained with a total yield of 67%.
