On July 7, 2010, Dong, Wei; Li, Xiaowen; Sun, Zhiliang published a patent.HPLC of Formula: 23256-42-0 The title of the patent was Long-acting antibacterial medicinal water-in-oil emulsion and its preparation method. And the patent contained the following:
The title emulsion is composed of water phase, oil phase, emulsifying agents and stabilizers. The oil phase is white oil 7# or 15#. The water-phase emulsifying agent is tween 80 and the oil-phase emulsifying agent is span 80. The emulsion is prepared by adding water-phase stabilizer into water at 40-45°, cooling to room temperature, dissolving antibacterial drug, adding tween 80, stirring to obtain water phase, adding 65-130° white oil 7# or 15# into oil-phase stabilizer, stirring, cooling to 50-60°, dissolving span 80, stirring to obtain oil phase, mixing water phase with oil phase, emulsifying and sterilizing. The antibacterial drug can be slowly released from the emulsion. The emulsion may be used as veterinary medicine for preventing and treating animal diseases in breeding field. The experimental process involved the reaction of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate(cas: 23256-42-0).HPLC of Formula: 23256-42-0
