  1. take this product, add anhydrous ethanol to dissolve and dilute to make a solution containing about 5mg per 1 ml as a test solution; Take an appropriate amount of azithromycin reference substance, add absolute ethanol to dissolve and dilute to prepare a solution containing about 5mg per 1 ml as a reference solution; According to thin layer chromatography (General 0502) test, absorb the above solutions respectively on the same silica gel G thin layer plate, with ethyl acetate-n-hexane-diethylamine (10:10:2) as the developing solvent, spread out, dry, spray with color developer (take sodium molybdate 2.5g, cerium sulfate lg, add 10% sulfuric acid solution to dissolve and dilute to 105 ml), heating at ° C. For several minutes. The position and color of the main spot displayed by the test solution should be the same as the position and color of the main spot of the reference solution.
  2. in the chromatogram recorded under the content determination item, the retention time of the main peak of the test solution should be consistent with the retention time of the main peak of the reference solution.
  3. The infrared absorption spectrum of this product should be consistent with that of the control (Spectrum set 772) or with that of the control. (In case of inconsistency, the appropriate amount of this product and the reference product should be taken, dissolved in acetone respectively, and volatilized to dryness at room temperature for determination.)
  4. two items (1) and (2) above can be selected as one item.
  5. developed by Pfizer Inc., USA, launched in 1988. Macrolide antibiotics, the antibacterial mechanism is similar to erythromycin, but the antibacterial spectrum is wider; The antibacterial activity of gram-positive bacteria is stronger, and the Gram-negative bacteria such as Haemophilus influenzae, salmonella, Escherichia coli, the antibacterial activity of Shigella was also strong. It has a good therapeutic effect on respiratory tract infection, skin and soft tissue infection and diseases caused by sensitive strains.
