4-Aminophenylacetic acid C화학적 특성, 용도, 생산
화학적 성질
light yellow to beige powder. Soluble in alcohols and alkalis, slightly soluble in hot water.용도
4-Aminophenylacetic acid is used as a non-translocated competitive inhibitor of the epithelial peptide transporter PepT1. It can be detected using HPLC, NMR techniques.제조 방법
p-aminophenylacetic acid is obtained by the reduction of 4-nitrophenylacetic acid. In a reactor, water, 4-nitrophenylacetic acid, and acetic acid are added. The mixture is stirred and heated to 90-95℃. Iron powder is added in portions and refluxed for 2 hours. The mixture is cooled to 40-50℃ and neutralized with sodium carbonate to pH=9, then filtered. The filtrate is further neutralized with acetic acid until pH=4, resulting in the precipitation of 4-aminophenylacetic acid. The yield is 95%.benefits
4-Aminophenylacetonitrile (4-APAN) is an arylacetonitrile and an active substrate for arylacetonitrilase, which gives 4-aminophenylacetic acid (4-APAA) on hydrolysis. 4-APAA is a precursor of 4-acetylaminophenylacetic acid, used in treating rheumatoid arthritis and actarit drugs. 4-APAA also possesses tuberculostatic activity and is helpful as a fibrinolysis inhibitor. In addition to the medical importance of this acid, several derivatives and compounds obtained from 4-APAA showed antimicrobial activity[1].Purification Methods
Crystallise the acid from hot water (60-70mL/g). [Beilstein 14 III 1182.]참고 문헌
