Used as a reference standard in analytical testing for the detection and quantification of thiacloprid residues in environmental and agricultural samples. Commonly applied in quality control laboratories to ensure compliance with pesticide residue regulations in food and water. Its high purity makes it suitable for calibration of instruments such as HPLC and GC-MS. Also utilized in research studies focused on neonicotinoid insecticide behavior, degradation, and impact on non-target organisms.
