4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the two functional groups are attached to the benzene ring across from one another in the para position) is an organic compound with the formula H 2 NC 6 H 4 CO 2 H. PABA is a white crystalline solid, [3] although commercial samples can appear gray.

Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value. It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic ...
4-Nitrobenzoic acid is an organic compound with the formula C 6 H 4 (NO 2)CO 2 H. It is a pale yellow solid. It is a precursor to 4-nitrobenzoyl chloride, the precursor to the anesthetic procaine and folic acid. It is also a precursor to 4-aminobenzoic acid. [6]
