Product Information

• Name: 4-(Aminosulfonyl)-7-fluoro-2,1,3-benzoxadiazole
• Synonyms: 7-Fluoro-2,1,3-benzoxadiazole-4-sulfonamideABD-F
• Brand: Biosynth
• Description: 4-(Aminosulfonyl)-7-fluoro-2,1,3-benzoxadiazole (AFB) is a reagent that has been used to detect the presence of galacturonic acid in cell culture. It is also a potent inhibitor of enzymes such as catalase and peroxidase. AFB binds to the sulfhydryl groups on enzymes, thereby preventing them from performing their catalytic function. The reducing power of AFB can be used as an indicator of the redox potentials in a sample. When AFB reacts with trifluoroacetic acid, it forms a disulfide bond and changes its color from yellow to blue. This change can be detected by UV spectroscopy or other analytical methods.
