| Abstract: | Objective To establish a preparation method of impurity olefinic compound and to conduct the structure confirma- tion. Methods The raw material difenidol hydrochloride was adopted to obtain the crytal by aeidization and abstraction,and its structure was confirmed by the infrared spectra（IR）,ultravoilet（UV）, HPLC and MS methods. Results The prepared crytal structure was con- firmed to be the impurity olefinic compound. The peak purity was 99.99%. Conclusion This method is simple to operate ,strongly spe- cific and highly sensitive, and the prepared olefinic compound crytal can be used for the quantitative determination of impurity olefinic compound in the related substances of difenidol hydrochloride raw material and preparations. |
