Used as a key reagent in organic synthesis, particularly in the preparation of nitrogen-containing heterocycles and pharmaceutical intermediates. It serves as a hydrazine equivalent in coupling reactions where controlled nitrogen transfer is required. Commonly employed in the synthesis of agrochemicals, dyes, and functional materials due to its stability and selective reactivity. Also utilized in the development of specialty polymers and as a building block in medicinal chemistry for constructing hydrazide and hydrazone derivatives with biological activity.
