The solution relates to salts of 2,4-diamino-5-  - (3,4-dimethoxybenzylpyrimidine)  of Formula I  NHa  in which  X represents hydrochloric acid, sulfuric acid  or acetic acid.  These salts serve to purify the crude 2,4-  -diamino-5- (3,4-dimethoxybenzyl) pyrimidine,  which is used in veterinary medicine  alone, or in combination with sulfonamides,  especially against coccidiosis.
