Considering the importance of phenolic compounds, e.g. The structure was confirmed by MS and 1H NMR. The cinnamic acid family has a common structure, namely, (E)‐3‐phenyl‐2‐propenoic acid, which has phenyl and carboxylic acid groups attached to the 1,2‐position of the vinyl group and thus can be regarded as a vinyl compound possessing both styrenic and acrylic structures. Cinnamic acids play key roles in the formation of other more complex phenolic compounds. For the determination of Phenylalanine Ammonia-lyase (PAL) Activity, I have to prepare standard curve of cinnamic acid, but I am not finding the right protocol for the preparation of standard curve. The cinnamic acid is soluble in dichloromethane at room temperature and thus before the bromine addition the reaction vessel holds a colourless solution.
