Properties

P-Nitrophenylacetic acid is light yellow acicular crystal, soluble in hot water, ethanol and benzene, slightly soluble in cold water. It is mainly used in medicine and other organic synthesis, and can also be used in biochemical research. The product is obtained by hydrolysis of p-nitrophenylacetonitrile: p-nitrophenylacetonitrile, concentrated sulfuric acid and water are mixed, heated and refluxed for 15min. Then the reactant is poured into ice water, crystallized, filtered, the filter cake is washed with ice water, and recrystallized with water to obtain p-Nitrophenylacetic acid. The yield is over 92%.
