Oxfendazole | 53716-50-0
Product Description: Ofendazole is a new type of highly effective, broad-spectrum and low toxic benzimidazole carbamate anti worm drug, Also known as sulfobenzimidazole or sulfobenzimidazole, it is an oxide on the sulfur atom of fenbendazole, and its chemical name is 5-benz-2-benzimidazole-methyl carbamate. Orfendazole, also known as sulfonylbenzimidazole. This product is a white or almost white powder with a slight special odor. This product is slightly soluble in methanol, acetone, chl... -
Mebendazole | 31431-39-7
Product Description: It is a broad-spectrum insect repellent with significant effects on killing larvae and inhibiting egg development. Both in vivo and in vitro experiments have shown that it can directly inhibit the intake of glucose by nematodes, leading to glycogen depletion and reduced adenosine triphosphate formation in the worm, making it unable to survive, but it does not affect blood sugar levels in the human body. Ultrastructural observation showed that the microtubules in the ... -
Flubendazole | 31430-15-6
Product Description: Flubenzimidazole is a synthetic benzimidazole insecticide that can inhibit nematode absorption and aggregation of intracellular microtubules. It can have a strong affinity with tubulin (the dimer subunit protein of microtubules) and inhibit microtubules from polymerizing in the absorption cells (i.e. the absorption cells in the intestinal cells of nematodes). It can be confirmed by the disappearance of (fine) cytoplasmic microtubules and the accumulation of secretory... -
Mucosolvan | 23828-92-4
Product Description: This product is a white to slightly yellow crystalline powder, almost odorless. Dissolve in methanol, slightly soluble in water, slightly soluble in ethanol. Mainly used as an expectorant, it can promote the elimination of viscous secretions in the respiratory tract and reduce the retention of mucus, thus significantly promoting sputum excretion. It is suitable for acute and chronic respiratory diseases accompanied by abnormal sputum secretion and poor sputum excreti...
