Structural formula: {0} (CAS {1})

Isorhamnetin is a monomethoxyflavone that is quercetin in which the hydroxy group at position 3' is replaced by a methoxy group. It has a role as a metabolite, an anticoagulant and an EC 1.14.18.1 (tyrosinase) inhibitor. It is a monomethoxyflavone, a tetrahydroxyflavone and a 7-hydroxyflavonol. It is functionally related to a quercetin. It is a conjugate acid of an isorhamnetin(1-).
