NEW MATERIAL:Compounds expressed by formula I (n is an integer of 0<=n<=20; R1 and R2 are H, O, halogen, saturated hydrocarbon, etc.: X<-> is monovalent anion). EXAMPLE:Carboxymethylsufonium. USE:Useful as a growth, breeding and oviposition promoter, health improver and vitality enhancer for various animals and a remedy for gastric, duodenal ulcer, gastritis, etc. PREPARATION:A compound expressed by formula II is reacted with a compound expressed by formula III to provide the compounds expressed by formula I. Among the compounds expressed by formula I, a compound in which n is an integer of 1<=n<=5; R1 and R2 are lower alkyl is especially more preferred. The compounds expressed by formula I have sufficient safety even if used as a feed for animals and food or drug for humans unless a large amount thereof is ingested at a time. |
