4-Aminobenzoic acid

Description:

4-Aminobenzoic acid, commonly known as PABA, is an aromatic amine and a derivative of benzoic acid. It features an amino group (-NH2) para to the carboxylic acid group (-COOH) on the benzene ring, which contributes to its chemical properties. PABA is a white crystalline solid that is soluble in water and alcohol, but less soluble in non-polar solvents. It has a melting point that typically falls within a specific range, indicating its stability under standard conditions. PABA is known for its role in the synthesis of folic acid and is utilized in various applications, including as a sunscreen agent due to its UV-absorbing properties. Additionally, it has been used in the production of dyes and as a precursor in the manufacture of pharmaceuticals. While PABA is generally considered safe, it can cause allergic reactions in some individuals. Its chemical formula is C7H9NO2, and it has a molecular weight that reflects its structure, making it an important compound in both organic chemistry and biochemistry.

4-Aminobenzoic acid

CAS: 150-13-0

4-Aminobenzoic acid is a chemical compound that can be used as an antibacterial agent in wastewater treatment. It has been shown to be effective against Aerobacter aerogenes and other bacteria. 4-Aminobenzoic acid is a basic compound with an aromatic ring and four amine groups. It is often used in the synthesis of polymers, pharmaceuticals, dyes, and pigments. The polymerase chain reaction (PCR) technique uses 4-aminobenzoic acid as a cofactor for DNA synthesis. Electrochemical impedance spectroscopy (EIS) is another application of this chemical compound in which it acts as a redox mediator in the electrical circuit. 4-Aminobenzoic acid also has been shown to have toxic effects on bowel disease cells, which may be due to its ability to react with nucleophilic groups on cell surfaces or by inhibiting the production of essential proteins or enzymes within the cells
