| Hazard Information | Back Directory | [Uses]
2,2′-Dihydroxyazobenzene was used as complexing reagent in determination of aluminum in human serum by ion-pair reversed-phase partition HPLC. | [General Description]
2,2′-Dihydroxyazobenzene is a small molecule inhibitor of ADP ribosyl cyclase and it attenuates angiotensin (Ang) II-induced hypertrophic responses. 2,2′-Dihydroxyazobenzene is formed during the oxidation of diclofenac by myeloperoxidase/hydrogen peroxide. |
