Aminobenzoic acid, also known as PABA (para-aminobenzoic acid), is an organic compound that belongs to the benzoic acid family. It is a white, crystalline substance that is soluble in water and alcohol. Aminobenzoic acid is commonly used in the production of dyes, pharmaceuticals, and as a sunscreen agent due to its ability to absorb ultraviolet (UV) light. In addition to its industrial applications, aminobenzoic acid plays a role in the synthesis of folic acid, an essential vitamin for human health. It is also found in some dietary supplements, as it is believed to support skin health and may have antioxidant properties.
