    A new drug classification system uses thin-layer chromatography (TLC), gas-liquid chromatography (GLC), and ultraviolet (UV) spectrophotometry for accurate identification. This method categorizes over 200 drugs based on chromatographic and spectrophotometric data.

    Area of Science:

    • Analytical Chemistry
    • Forensic Science
    • Pharmaceutical Analysis

    Background:

    • Accurate drug identification is crucial in forensic and clinical settings.
    • Existing classification methods may lack comprehensive analytical approaches.
    • Chromatographic and spectrophotometric techniques offer powerful tools for chemical analysis.

    Purpose of the Study:

    • To develop and present a novel classification system for drugs.
    • To integrate thin-layer chromatography (TLC), gas-liquid chromatography (GLC), and ultraviolet (UV) spectrophotometry into a unified classification scheme.
    • To provide a practical procedure and a catalog of classified drugs.

    Main Methods:

    • Classification of drugs using thin-layer chromatography (TLC) based on zone division relative to mixed drug standards.

  • Integration of TLC, GLC, and UV spectrophotometry for comprehensive drug profiling.

    • Main Results:

    • A systematic classification procedure for drugs has been established.
    • The system successfully categorizes drugs based on distinct chromatographic and spectrophotometric properties.
    • A comprehensive list of over 200 classified drugs is presented.

    Conclusions:

    • The described multi-technique approach provides a robust system for drug classification.
    • This method enhances the accuracy and efficiency of drug identification in analytical laboratories.
    • The presented classification system and drug list serve as a valuable resource for researchers and practitioners.
