Oxidation is considered an important reaction in organic synthesis. FUJIFILM Wako deal with metallic oxidation catalysts and organic catalysts that are supported on a solid phase. This fixation facilitates the post-treatment of catalysts and allows them to be reused. In addition, osmium, which is a toxic metal, can be used safely after fixation. Furthermore, organic and nitroxyl radical oxidizers, which act like catalysts and exhibit high activity, are available. We also deal with AZADO® series, which are highly active nitroxy radical oxidizers.
