Used primarily as an intermediate in the synthesis of pharmaceuticals, especially in the production of non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics. It serves as a building block in organic reactions where controlled substitution on the aromatic ring is required. Its acetylated amine group provides stability during reaction sequences and can be deprotected or modified to form active drug compounds. Commonly found in research settings for developing pain relief and fever-reducing medications.
