4-Aminophenylacetic acid Use and Manufacturing
From the reduction of p-nitrophenylacetic acid. Add water, p-nitrophenylacetic acid and acetic acid to the reactor, stir and heat to 90-95℃, add iron powder in portions, add reflux for 2h, cool to 40-50℃, neutralize with sodium carbonate to make pH=9, filter. The filtrate was neutralized with acetic acid until pH=4, and p-aminophenylacetic acid was precipitated. The yield was 95%.
It is a non-translocated competitive inhibitor of the epithelial peptide transporter PepT1
