    Three quinoline amines found in greyhound urine can interfere with drug analysis, particularly in ultraviolet spectrometry. Analytical data for these compounds and related substances are provided to aid accurate testing.

    Area of Science:

    • Analytical Chemistry
    • Forensic Science
    • Veterinary Toxicology

    Background:

    • Greyhound urine analysis is crucial for detecting performance-enhancing drugs.
    • Certain endogenous compounds can interfere with analytical methods.
    • Quinoline amines are identified as potential interferents in greyhound biological samples.

    Purpose of the Study:

    • To identify and characterize quinoline amines in greyhound urine.
    • To assess the interference potential of these amines in drug analysis.
    • To provide reference analytical data for these compounds.

    Main Methods:

    • Infrared spectrometry
    • Ultraviolet spectrometry
    • Fluorometry
    • Thin-layer chromatography

  • Gas chromatography
  • Mass spectrometry

    • Main Results:

    • Three quinoline amines (2-aminomethylquinoline, 2-hydroxymethylquinoline, quinaldine) were identified in greyhound urine.
    • These amines exhibit high extinction coefficients, posing a significant interference risk in ultraviolet spectrometry.
    • Reference data for seven quinoline amine compounds were generated.

    Conclusions:

    • The presence of specific quinoline amines in greyhound urine necessitates careful consideration during drug testing protocols.
    • Accurate identification and quantification of drugs in greyhound samples require accounting for these endogenous interferents.
    • The provided analytical data will assist in developing more robust and reliable greyhound doping control methods.
