Nivalenol from Fusarium nivale-13C15 is primarily used as an internal standard in analytical chemistry for the precise quantification of nivalenol in various samples. It is especially valuable in food safety testing, where accurate detection of mycotoxins is critical to ensure compliance with regulatory standards. This labeled compound aids in the development of reliable methods for monitoring nivalenol contamination in grains, cereals, and other agricultural products. Additionally, it is employed in research studies to investigate the toxicological effects of nivalenol and its impact on human and animal health. Its use enhances the accuracy and reproducibility of analytical results in both laboratory and industrial settings.
