Identification | 1. Into 10mg of the substance to be examined, add 2ml of water for dissolving and 3ml of hydroxylamine hydrochloride solution, shake well, and allow to stand for 3min. Add 1ml of acid ferric ammonium sulfate, shake well, and then the solution shows red brown. 2. Add water to dilute 20mg of the substance to be examined to 100ml, accurately pipette 5ml, and dilute with water to 50ml, to obtain solution with concentration of 20ug/ml with water. The maximum absorption should exist at 293nm, and the minimum absorption should exist at 241nm. 3. In the chromatogram of the assay, the retention time of the major peak in the chromatogram obtained with the test solution corresponds to that of the major peak in the chromatogram obtained with reference solution. 4. The infrared spectrum of the substance to be examined corresponds to that of the reference spectrum. | 1.Conform 2.Conform 3.Conform 4.Conform | |
