Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting the central nervous system. It plays a key role in the preparation of pyridyl-containing compounds that exhibit biological activity, such as receptor agonists or enzyme inhibitors. Its reactivity allows for the introduction of functional groups through nucleophilic substitution, making it valuable in medicinal chemistry for building complex molecules. Also utilized in agrochemical synthesis for creating novel pesticides and herbicides due to its ability to enhance molecular stability and bioavailability.
