Take about 0.2g of this product, accurately weigh it, add 20ml of water to dissolve, slowly add 40ml of 10% trichloroacetic acid solution under stirring, and leave it for 2 hours. , the precipitation was first washed with a small amount of 10% trichloroacetic acid solution, and then washed with 20 ml of cold water below 10 ° C in several batches, and then placed in a phosphorus pentoxide desiccator to dry under reduced pressure to constant weight, and accurately weighed. The weight of the obtained precipitate was the same as Multiply by 0.8487 to get the weight of C17H19N3O.CH4O3S in the test product.


Dosage and Administration
1. Intramuscular or intravenous injection for vasospasm, 5 mg/time, 1-2 times/day.
