Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of analgesic and anti-inflammatory drugs. It serves as a building block in organic synthesis due to the presence of both amino and hydroxyl functional groups, allowing for multiple modification pathways. Commonly employed in the development of azo dyes and pigments thanks to its ability to undergo diazotization and coupling reactions. Also utilized in the preparation of certain heterocyclic compounds for use in medicinal chemistry research.
