Abstract

Presents the characterization and purity assessment of deoxynivalenol (DON) obtained from two commercial sources. Confirmation of DON structural identity by H and C-nuclear magnetic resonance (NMR) spectroscopy, gas chromatography (GC) and infrared total reflectance spectroscopy; Establishment of complete assignment for all signals; Similarity of the chromatograms for both samples; Confirmation of the DON structure; Absence of differences in the purity.
