Embodiment 3
[0093] Embodiment 3 stability test
[0094] Take an appropriate amount of sample (100 ~ 200mg), spread it in a clean petri dish, and spread it into a thin layer with a thickness of ≤ 5mm. Humidity), light (visible light 4500lx±500lx, ultraviolet light not less than 0.7W h / m 2 , 25±2°C, 60%±5% relative humidity) and normal temperature (25±2°C, 65%±5% relative humidity) for stability test (high temperature, high humidity light and room temperature for 10 days), Sampling was carried out on the 5th day and 10th day respectively, and the impurity content was calculated by the peak area normalization method using an HPLC instrument. The instrument and test conditions are shown in Table 2.
