Used primarily as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves as a building block in the preparation of nitrogen-containing heterocyclic systems, which are common in bioactive molecules. Its nitroso and piperazine functionalities allow for selective transformations, making it valuable in medicinal chemistry for constructing complex drug candidates. It has been explored in research settings for potential applications in central nervous system agents and receptor modulators due to the structural features it imparts. Handling requires caution due to potential instability and toxicity associated with nitroso compounds.
