Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block in the development of sulfonamide-based bioactive compounds due to its stability and reactivity. Commonly employed in the synthesis of herbicides and fungicides, it contributes to the structural framework that enhances biological activity. Also utilized in research settings for the development of new synthetic routes and catalytic processes. Its ability to act as a directing group in C–H activation reactions makes it valuable in advanced organic transformations.
