Used primarily as an intermediate in the synthesis of organophosphorus compounds, this chemical plays a key role in the development of certain pesticides and flame retardants. Its reactivity allows for the introduction of phosphate groups into complex molecules, enhancing their biological activity or thermal stability. It is also employed in research settings for the preparation of novel phosphorylated compounds with potential applications in agrochemicals and materials science. Due to its reactivity and toxicity, handling requires strict safety controls.
