Overview | 2, 4-dichloro-6-nitrophenol is useful as a pharmaceutical synthesis intermediate. Such as can be used for the preparation of pentachlorolithamide (oxyclothanide), also known as hydroxychlorolithamide, hydroxychlorolithidine and hydroxychlorazamine, which belongs to halogenated salicylidene aniline compounds, is a kind of salicylanilide anthelmintics, is currently mainly used for the treatment and control of cattle and sheep and other animal trematodiasis. Similar to other salicylanilide anthelmintics, pentachlorolithamide is an oxidative phosphoric acid dissolving coupling agent, and its mechanism is to inhibit the phosphorylation process of the mitochondria of the worm and prevent the adenosine triphosphate (ATP) in the worm. That is, the production of energy, which leads to the death of the worm due to the disorder of energy metabolism. |
Application | The main application mode of pentachlorinosamide is: as a single oral dose, it is administered in combination with levamisole hydrochloride or ofendazole, or mixed in the form of powder into the feed for administration. In recent years, it has been found that pentachlorolithamide not only has good anthelmintic effect on Fasciola hepatica, but also has activity on tapeworms and nematodes, and it has low toxicity and no residue, therefore, it has been widely used in the anthelmintic market. |
