摘要:
The novel compound according to the invention 3-(2,2,2-trimethylhydrazinium)-propionate has the general formula:(CH.sub.3).sub.3 NNHCH.sub.2 CH.sub.2 COO.2H.sub.2 O.The method for preparing this novel compound comprises passing a solution of 3-(2,2,2-grimethylhydrazinium) alkylpropionate of the formula:X.sup.- (CH.sub.3).sub.3 N.sup.+ NHCH.sub.2 CH.sub.2 COORwherein X is Cl, Br, I, CH.sub.3 SO.sub.4, R is a loawer alkyl, through a column with a strongly-basic anion exchange resin, followed by isolation of the desired product. The growth stimulator for animals and fowl contains the novel compound, i.e. 3-(2,2,2-trimethylhydrazinium)-propionate as the active principle.
