This study provides corrected Rf values for 170 common pesticides using Thin Layer Chromatography (TLC). These validated data are crucial for accurate toxicological analysis and pesticide identification.

Area of Science:

Analytical Chemistry
Environmental Science
Toxicology

Background:

Accurate identification of pesticides is vital in toxicological analysis.
Thin Layer Chromatography (TLC) is a common technique for pesticide analysis.
Standardized data for pesticide Rf values are needed for reliable results.

Purpose of the Study:

To report corrected Rf (Rf(c)) values for 170 frequently encountered pesticides.
To provide a reliable dataset for pesticide identification in toxicological studies.
To establish standardized chromatographic data for common pesticides.

Main Methods:

Thin Layer Chromatography (TLC) was employed.
Silica gel was used as the stationary phase.
Three binary solvent systems were utilized for chromatographic separation.
