Aminobenzoic acids are a group of organic compounds that contain an amino group and a carboxylic acid group attached to a benzene ring. The most common form is para-aminobenzoic acid (PABA), which is often used in sunscreen products due to its ability to absorb ultraviolet light. These compounds play a role in various biological processes and can be found in some vitamins. In addition to their use in cosmetics, aminobenzoic acids are important in the synthesis of dyes and pharmaceuticals. They can also serve as intermediates in the production of other chemical compounds. Their unique structure allows for diverse applications in both industrial and medical fields.
