Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with anti-inflammatory and analgesic properties. It serves as a building block in agrochemicals for creating herbicides and pesticides due to its ability to enhance bioactivity. Also employed in the preparation of functional materials, including dyes and specialty polymers, where its heterocyclic structure contributes to thermal stability and electronic properties. Its derivatization is common in medicinal chemistry for structure-activity relationship (SAR) studies.
