Used primarily as an intermediate in organic synthesis, especially in the preparation of pharmaceuticals and agrochemicals. It participates in nitrosation reactions and can serve as a building block in the development of nitrogen-containing heterocyclic compounds. Due to the presence of both nitroso and amine functionalities, it is valuable in coordination chemistry and in the design of ligands for metal catalysts. Also finds use in research settings for studying reaction mechanisms involving nitrosamines. Handle with care due to potential toxicity and mutagenic properties associated with nitroso compounds.
