Used as a reference standard in analytical testing to detect and quantify deoxynivalenol contamination in food and feed, particularly in grains such as wheat, barley, and corn. Plays a critical role in food safety monitoring programs to ensure compliance with regulatory limits for mycotoxins. Employed in research to study the stability, transformation, and detoxification of deoxynivalenol during processing and storage. Also utilized in immunoassay development and validation of detection methods like ELISA and HPLC-MS.
