Used primarily as an analytical reference standard in environmental and toxicological studies, this compound aids in the detection and quantification of organophosphorus pesticide metabolites. It is particularly valuable in research focused on pesticide degradation pathways and metabolic byproducts in biological and environmental samples. Due to its structural similarity to active organophosphate pesticides, it serves as a model compound for studying inhibition mechanisms of cholinesterase enzymes, supporting the development of antidotes and monitoring exposure in occupational health settings. Its stability and defined reactivity also make it useful in method validation for chromatographic and mass spectrometric analyses.
