Used as a reference standard in analytical laboratories for the accurate determination of fluralin residues in environmental samples, soil, and agricultural products. Commonly employed in gas chromatography (GC) and high-performance liquid chromatography (HPLC) methods to calibrate instruments and validate testing procedures. Ensures reliable quantification in pesticide residue monitoring programs and supports regulatory compliance in food safety and environmental protection. Also utilized in research studies focused on herbicide persistence, degradation pathways, and ecological impact assessments.
