Used as a reference standard in analytical laboratories for the detection and quantification of benalaxyl residues in environmental samples, agricultural products, and food matrices. Its presence in methanol allows direct injection into chromatographic systems like HPLC or GC-MS for calibration and method validation. Widely applied in quality control and pesticide residue monitoring programs to ensure compliance with regulatory limits. Also utilized in research studies focusing on fungicide degradation, metabolism, and efficacy against oomycete pathogens such as Phytophthora and Pythium species.
