Used as an analytical reference standard in environmental testing to detect and quantify pesticide residues, particularly in water and soil samples. Its structure mimics certain herbicidal compounds, making it valuable in studying degradation pathways and metabolic byproducts of phenoxy-based pesticides. Also employed in research laboratories to develop and validate chromatographic methods like HPLC and GC-MS for pesticide analysis. Due to its stability and defined reactivity, it serves as a model compound in studies assessing the environmental fate of chlorinated aromatic substances.
