4-(Difluoromethoxy)nitrobenzene C화학적 특성, 용도, 생산
화학적 성질
Pale Yellow Crystal.
용도
4-(Difluoromethoxy)nitrobenzene is an industrial chemical that can be used to make 4-fluoro-3-pyridinol (F3P), a compound that has potential as a new drug for the treatment of cancer. The synthesis of F3P begins with the reaction of 4-(difluoromethoxy)nitrobenzene and potassium hydroxide in methanol, which yields 4-fluoro-3-hydroxypyridine. This product is then reacted with ammonia gas and pyridine to yield F3P. The final step involves heating the product at high temperature with nitric acid, which yields nitrobenztriazole.
일반 설명
4-(Difluoromethoxy)nitrobenzene (1-(difluoromethoxy)-4-nitrobenzene) can be synthesized by reacting 4-nitrophenol with KOH, water and methanol.
