Methyl p-chlorocinnamate is an organic chemical, often used in industry, pharmaceutical industry, etc., obtained by reacting chlorobenzaldehyde with acetic anhydride. The chlorobenzene formaldehyde, acetic anhydride and sodium acetate with reaction 13h under 180 ℃. After the reaction, it is slightly cold. Pour into the water, filter and wash the filter cake with water. Dissolve the cake repeatedly with ammonia until only a small amount of brownish-yellow sticky remains remain. The ammonium salt solution was filtered, then the chlorocinnamic acid was precipitated out with 3N dilute sulfuric acid, and the product was filtered and dried.

Methyl p-chlorocinnamate is an organic synthesis intermediate, mainly used to synthesize methyl bromomethyl cinnamate from the upstream raw material of the antithrombotic agent ozagrel sodium. The methyl methylanilate was prepared by N- butyl diimide bromide bromide and the total yield was 67%.
P-Hydroxycinnamic Acid, also known as 4-Hydroxycinnamic acid, is a radical scavenging effects of antioxidant, compared with other tyrosinase inhibitor, the hydroxy cinnamic acid and ether hydroxy cinnamic acid and other non-toxic odorless, good permeability, and is considered a good candidate material used as a skin whitening agent.
