NEW MATERIAL:A 1-{4-[4-( fluoroalkylmethyl-thio-, -sulfinyl- or sulfonyl- )phenoxy]phenyl}-1,3,5-triazine-2,4,6(1H, 3H, 5H)-trione shown by the formula I (R<f> is fluoroalkyl; X and Y may be the same or different, H, lower alkyl, lower alkoxy, or halogen; R is lower alkyl; n is 0-2) or its salt. EXAMPLE:1{3,5-Dichloro-4-[4-( beta, beta, beta-trifluoroethylsulfonyl )-phenoxy]-phenyl}-3- methyl-1,3,5-triazine-2,4,6-(1H, 3H, 5H)trione. USE:Useful as a coccidiostat for men and various kinds of animal species. PREPARATION:A urea shown by the formula II is reacted with a carbonyl isocyanate shown by the formula III (R<2> is halogen, etc.) to give a compound shown by the formula I .
