CAS :7-Fluorobenzo-2-oxa-1,3-diazole-4-sulfonic acid ammonium is a fluorescent derivative that is used in clinical pathology to study human metabolism. The compound reacts with blood cells to form a fluorescent derivative that can be detected by use of a fluorescence detector. A sample preparation technique is required to prepare the blood samples before analysis. 7-Fluorobenzo-2-oxa-1,3-diazole-4-sulfonic acid ammonium has been shown to react with disulfide bonds and endogenous substances, such as glutathione, dopamine and serotonin. The detection sensitivity for this compound is approximately 10 pM.Formule :C6H6FN3O4SDegré de pureté :Min. 95%Couleur et forme :White PowderMasse moléculaire :235.19 g/mol7-Fluoro-2,1,3-benzoxadiazole-4-sulfonate (ammonium salt)
