Synthesis method

1. It is formed by the condensation of p-nitroanilide and urea.

2.It is prepared by the cyclization of 4,4′-p-nitro diphenyl urea, acetylacetone and urea. Or it can be prepared from 4,4′-p-nitro diphenyl urea and 2-hydroxy-4,6-dimethylpyrimidine.


1. It has a good preventive and therapeutic effect on Eimeria tenella in the cecum, Eimeria tenella in the small intestine, Eimeria giantis and Eimeria Bordoni. For broiler or pullet use only, not for laying hens.

2.It has the advantages of high efficiency, low toxicity, stable performance and low drug resistance. It has a good preventive effect on chicken cecal coccidia, Ehrlichia acervicis, Ehrlichia gigantea, and poisonous Ehrlichia. It is effective against the second generation schizonts of coccidia and is highly safe. Used to prevent chicken and turkey ballworm diseases.
