설명

일반 설명

4-Aminobenzoic acid (4-ABA) acts as an bacterial cofactor and participates in the synthesis of folic acid. It is a versatile reagent for structure extension through linear hydrogen-bonding associations, involving both the carboxylic acid and amine functional groups. Formation of 4-ABA monolayer film on glassy carbon electrode (GCE) by amino cation radical method has been described. Molecular adducts of 4-ABA have been prepared and their characterization by infrared spectroscopy and X-ray diffration methods have been reported.

애플리케이션

4-Aminobenzoic acid may be used in the following studies:

• Covalent modification of glassy carbon electrode.
• Synthesis of 1,4-(2-chlorobenzylidene)aminobenzoic acid (Schiff base).
• Spectrophotometric determination of the trace amounts of dopamine, methyldopa and levodopa.
• Synthesis of 1:1 proton-transfer compound with 5-sulfosalicylic acid.
