化学的特性
4-Hydroxyphenylacetic acid is a white to cream or light tan crystalline powder. sublimation. Insoluble in cold water, soluble in hot water, ether, ethanol, ethyl acetate. In the case of ferric chloride, it is a purple-green precipitate. It is used as a pharmaceutical raw material for the synthesis of cephalosporin antibiotics, antipyretic analgesics.
使用
A compound present in olive oil. An important fine chemical intermediate with broad prospects for application development.
定義
ChEBI: 4-hydroxyphenylacetic acid is a monocarboxylic acid that is acetic acid in which one of the methyl hydrogens is substituted by a 4-hydroxyphenyl group. It has a role as a plant metabolite, a fungal metabolite, a human metabolite and a mouse metabolite. It is a monocarboxylic acid and a member of phenols. It derives from an acetic acid. It is a conjugate acid of a 4-hydroxyphenylacetate.
製造方法
4-Hydroxyphenylacetic acid is synthesized by diazotization and hydrolysis of 4-aminophenylacetic acid.
4-aminophenylacetic acid and alkali solution are prepared into sodium salt, and then sulfuric acid is added. Cool to 0°C, control the temperature at 0-5°C, and add sodium nitrate solution dropwise, and the reaction is completed for 0.5h. The obtained diazonium was added dropwise to dilute sulfuric acid at 90-95°C for about 1 hour, and the reaction was continued for 1 hour. The reaction solution was decolorized and filtered, cooled and extracted with ethyl acetate, and the extract was recovered with ethyl acetate to obtain 4-Hydroxyphenylacetic acid. The yield is about 85%.
純化方法
Crystallise the acid from water or Et2O/pet ether. The p-bromophenacyl ester has m 117o (from EtOH). [Beilstein 10 II 112, 10 III 430, 10 IV 543.]
