Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of antibiotics and anti-inflammatory agents. It also serves in the preparation of dyes and pigments due to its aromatic structure and functional groups that allow for various chemical modifications. Its hydroxyl and amino groups make it suitable for use in chelating agents and antioxidants, where it can stabilize metal ions and scavenge free radicals. Additionally, it finds application in research settings for the development of novel organic compounds and in the study of reaction mechanisms involving substituted benzoic acids.
