The Uses of 4-Nitrocinnamic acid

4-Nitrocinnamic Acid (cas# 619-89-6) is a compound useful in organic synthesis.

Preparation

Synthesis of 4-nitrocinnamic acid: 4-nitro-trans-cinnamonitrile, concentrated hydrochloric acid and water were heated and refluxed for 8h, and left standing overnight. The precipitate was filtered out, dissolved in hot 30% sodium hydroxide solution, the insoluble matter was filtered off, the filtrate was acidified with 50% sulfuric acid to precipitate precipitation, the crude product was filtered, and recrystallized with ethanol to obtain 4-nitrocinnamic acid.
