About Azoxystrobin 97% TC
Azoxystrobin is an aryloxypyrimidine having a 4,6-diphenoxypyrimidine skeleton in which one of the phenyl rings is cyano-substituted at C-2 and the other carries a 2-methoxy-1-(methoxycarbonyl)vinyl substituent, also at C-2. An inhibitor of mitochondrial respiration by blocking electron transfer between cytochromes b and c1, it is used widely as a fungicide in agriculture. It has a role as a mitochondrial cytochrome-bc1 complex inhibitor, a xenobiotic, an environmental contaminant, an antifungal agrochemical and a quinone outside inhibitor. It is a nitrile, an aryloxypyrimidine, an enoate ester, an enol ether, a methyl ester and a methoxyacrylate strobilurin antifungal agent.
