It is a white to grey powder; insoluble in water, slightly soluble in acetone, chloroform, Ether and methanol. Its chemical designation is [5-(phenylsulfinyl)-1H- benzimidazol-2-yl] carbamic acid methyl ester.

Function
Oxfendazole is a new broad-spectrum insecticide. Its efficacy is more than twice higher than that of benzimidazole. For all kinds of gastrointestinal nematode adults of sheep, cattle and pigs, the worm reduction rate is 95-100% at 23.5-5mg/kg dose. The reduction rate for each stage larva was 91-98%. Also effective on Hymenolepis nana and Dictyocaulus, but the effect of poor pig whipworm. This product has low toxicity and good tolerance. The rat LD50 is more than 6400mg/kg.
