| Abstract: | Objective To analyse the method for content determination of tetracaine hydrochloride in glycerin solution of tetracaine hydrochloride by ultraviolet spectrophotometry.Mehtods The content of tetracaine hydrochloride in glycerin solution of tetracaine hydrochloride was determined by ultraviolet spectrophotometry and then its results were compared with those of dead stop titration.Results The maximal absorption of tetracaine hydrochloride was at the wavelength of 310nm,and its regression equation was A=0.07510C+0.00369,r=9999;its average recovery was 99.81% while the average labelled content was 98.46% and RSD was 1.15%.Conclusion This method is simpler than the dead stop titration with no significant difference in their results. |
