| use | for organic synthesis. Mainly used in medicine and other organic synthesis, and can also be used for biochemical research |
| production method | obtained by hydrolysis of p-nitrophenylacetonitrile. Mixed p-nitrophenylacetonitrile, concentrated sulfuric acid and water, heated and refluxed for 15min. Then pour the reactants into ice water, precipitate crystallization, filter, wash the filter cake with ice water, and then recrystallize with water to obtain p-nitrophenylacetic acid. The yield is over 92%. |
