    Area of Science:

    • Analytical Chemistry
    • Biochemistry

    Background:

    • Phospholipids are crucial biological molecules.
    • Accurate detection on thin-layer chromatograms is essential for analysis.
    • Existing detection methods, like molybdenum blue, have limitations.

    Purpose of the Study:

    • To evaluate ammonium pentachlorooxomolybdate as a spray reagent for phospholipid detection.
    • To compare its efficacy against traditional reagents.

    Main Methods:

    • Thin-layer chromatography (TLC) was employed.
    • Ammonium pentachlorooxomolybdate in 7-9 N sulfuric acid was used as a spray reagent.
    • Detection sensitivity and background color development were assessed.

    Main Results:

    • Ammonium pentachlorooxomolybdate proved to be an excellent reagent for specific phospholipid detection.
    • The new reagent demonstrated greater sensitivity compared to the standard molybdenum blue reagent.
    • It effectively prevented the development of background blue color during prolonged exposure.

    Conclusions:

    • Ammonium pentachlorooxomolybdate is a highly effective and sensitive reagent for visualizing phospholipids on TLC plates.
    • This reagent offers significant advantages over existing methods, improving analytical accuracy and reducing experimental artifacts.
