Aflatoxin M2 is primarily used in research and analytical settings to study its effects and develop detection methods. It is often employed in laboratory studies to understand its toxicity, metabolism, and impact on health, particularly in relation to food safety. Researchers use it to validate analytical techniques for detecting aflatoxins in food products, especially dairy, as it is a metabolite found in milk. Additionally, it serves as a reference standard in quality control processes to ensure accurate measurement and regulation of aflatoxin contamination in food and feed industries.
