Fluralin standard solution is primarily used in analytical laboratories for the calibration and validation of instruments involved in pesticide residue analysis. It serves as a reference standard to accurately identify and quantify fluralin in environmental samples such as soil, water, and agricultural products. The solution is essential in quality control processes within food safety, environmental monitoring, and regulatory compliance testing. It ensures reliable measurement of fluralin levels, supporting studies on pesticide persistence, degradation, and potential ecological impact.
