Used primarily as an intermediate in organic synthesis, especially in the preparation of pharmaceuticals and agrochemicals. It serves as a hydrazine derivative that can participate in the formation of heterocyclic compounds, such as pyrazoles and triazoles, which are common scaffolds in bioactive molecules. Its reactivity allows for the introduction of nitrogen-containing functional groups in complex molecule assembly. Due to its hydrazine core, it can also act as a reducing agent in selective transformations. Commonly handled with care because of potential instability and toxicity.
