Used primarily as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its nitroso functional group allows it to participate in various reduction and condensation reactions, making it valuable for constructing nitrogen-containing heterocycles. It is also employed in the preparation of functionalized piperazines, which are key structural motifs in drug discovery, especially in central nervous system agents and bioactive molecule design. Due to its reactivity, it is handled under controlled conditions to avoid decomposition or unwanted side reactions.
