Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs. Its structure allows for easy modification, making it valuable in creating compounds with specific biological activity. Commonly employed in the production of antipsychotics, antidepressants, and antihistamines. Also utilized in agrochemicals for the development of certain pesticides and herbicides due to its stability and reactivity profile. Frequently chosen in medicinal chemistry for lead optimization because of its favorable pharmacokinetic properties.
