This study details thin-layer chromatography data for 20 common beta-blockers, crucial for toxicological analysis. The findings provide essential reference values for identifying these drugs in forensic and clinical settings.

Area of Science:

Analytical Chemistry
Forensic Toxicology

Background:

Beta-blockers are widely prescribed cardiovascular drugs.
Accurate identification of beta-blockers is critical in toxicological investigations.
Existing chromatographic data may not cover all commonly encountered beta-blockers.

Purpose of the Study:

To establish reliable thin-layer chromatographic data for 20 frequently used beta-blockers.
To provide reference Rcf-values for toxicological analysis.
To aid in the identification and quantification of beta-blockers in biological samples.

Main Methods:

Thin-layer chromatography (TLC) was employed.
Silica gel was used as the stationary phase.
Ten solvent systems, based on German Research Foundation (DFG) guidelines, were utilized.

Main Results:

Corrected Rf-values (Rcf-values) were determined for 20 beta-blockers.
The data provides a comprehensive chromatographic profile for these compounds.
The chosen solvent systems demonstrated effective separation of the tested beta-blockers.

Conclusions:

The generated Rcf-values serve as valuable data for toxicological screening.
This study enhances the capabilities for identifying beta-blockers in forensic casework.
The standardized chromatographic methods ensure reproducibility and reliability in analysis.
