Flavin adenine dinucleotide disodium salt hydrate is a chemical compound that can be used as a substrate for nitrate reductase in the presence of molecular oxygen. Flavin adenine dinucleotide disodium salt hydrate can be used to identify mollicutes and diagnose radiation-induced lesions. The reaction mechanism involves the conversion of riboflavin 5'-adenosine monophosphate to riboflavin 5'-adenosine diphosphate by an enzyme called nitrate reductase, which are detected by a fluorescence detector.
