Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its structure allows for easy modification and incorporation into more complex molecules, making it valuable in the design of bioactive compounds. Commonly employed in sulfonylation reactions to introduce the piperazine moiety, which is prevalent in many drug molecules due to its favorable pharmacokinetic properties. Also utilized in the preparation of sulfonamide-based inhibitors in medicinal chemistry research.
