Used primarily as an intermediate in organic synthesis, especially in the preparation of pharmaceuticals and agrochemicals. It plays a key role in the development of nitrogen-containing heterocyclic compounds, which are common structural motifs in bioactive molecules. Its reactivity allows for functionalization at multiple sites, making it valuable in the construction of complex molecules. Also utilized in research settings for the synthesis of dyes and functional materials. Due to its nitroso group, it can participate in cycloaddition and condensation reactions, enabling the formation of new carbon-nitrogen bonds. Handle with care as nitroso compounds may pose health and safety risks.
