identification

1. take an appropriate amount of fine powder of this product (about 0.lg of sulfadiazine), add 3ml of 0.4% sodium hydroxide solution and 3ml of water respectively, shake, filter, and take the filtrate and 0.5ml of copper sulfate test solution, that is, a cyan-green precipitate is generated, which changes to a purple-gray color after being placed.
2. take an appropriate amount of fine powder of this product (about 25mg of trimethoprim), add 5ml of 0.4% sodium hydroxide solution, shake well, add 5ml of chloroform, shake extraction, and take 5ml of chloroform solution and dilute sulfuric acid, after shaking, 2 drops of iodine solution were added to form a brown precipitate in the dilute sulfuric acid layer.
3. in the chromatogram recorded under the content determination item, the retention time of the two main peaks of the test solution should be consistent with the retention time of the corresponding two main peaks of the control solution.
4. take an appropriate amount of fine powder of this product (about 50mg equivalent to sulfadiazine) to show the identification reaction of the first aromatic amine (General rule 0301).

examination

• dissolution of this product, according to the dissolution and release determination method (General 0931 second method), with 0.lmol/L hydrochloric acid solution 1000ml as the dissolution medium, the speed is 75 revolutions per minute, according to the law, after 60 minutes, take 10ml of the solution, filter, take 5ml of the continued filtrate with precision, in a 25ml measuring flask, dilute to the scale with mobile phase, shake well, and measure according to law according to the method under the item of determination containing child, and calculate the dissolution amount of sulfadiazine and trimethoprim in each tablet. The limit shall be 70% of the labeled amount and shall be in accordance with the regulations.
