The time required for this reaction is less than</p>Formule :C15H12ClNO2Degré de pureté :Min. 95%Couleur et forme :White To Off-White SolidMasse moléculaire :273.71 g/mol4'-Benzyloxy-3'-nitroacetophenone
CAS :<p>4'-Benzyloxy-3'-nitroacetophenone is a nitro-substituted aromatic compound that has been studied as an inhibitor of xanthine oxidase. It is also known to inhibit cytochrome P450 and nitric oxide synthase. The molecular modeling study showed that 4'-benzyloxy-3'-nitroacetophenone binds to the active site of xanthine oxidase and blocks the binding site for xanthine, which stops the conversion of xanthine to uric acid. This inhibition leads to a decrease in urate production, which can help prevent gout attacks.</p>Formule :C15H13NO4Degré de pureté :Min. 95%Masse moléculaire :271.27 g/molTiotropium bromide monohydrate
