M-aminophenol
operation in the dark. Take an appropriate amount of this product, accurately weigh it, add the mobile phase to dissolve and quantitatively dilute it to make a solution containing about 1 mg per 1 ml, which is used as a test solution (ready to use new system); Take an appropriate amount of M-aminophenol reference, precision weighing, plus mobile phase dissolution and quantitative dilution to make a solution containing about 1.8ug per 1 ml, as a reference solution. According to high performance liquid chromatography (General rule 0512) test ^ using eighteen alkyl silane bonded silica gel as filler, phosphate buffer solution (take disodium hydrogen phosphate 3.4g and sodium dihydrogen phosphate g, add appropriate amount of water to dissolve, add 23ml of 10% tetrabutylammonium hydroxide solution, add water to ML) Methanol (90:10) as mobile phase, the detection wavelength was 280nm. In addition, appropriate amount of this product and M-aminophenol reference substance were added with mobile phase to make a mixed solution containing about 1 mg of pasniazid and 1.8ug of M-aminophenol per 1 ml, and 20ul was injected into human liquid chromatograph, the number of theoretical plates shall not be less than 5000 based on the M-aminophenol peak. The resolution of isoniazid peak, M-aminophenol peak and p-aminosalicylic acid peak shall meet the requirements. The sample solution and the reference solution were respectively injected with 20 u1 for human liquid chromatograph. If there are chromatographic peaks in the chromatogram of the test solution that are consistent with the retention time of the M-aminophenol peak, the peak area shall be calculated according to the external standard method, and shall not exceed 0.25%.
chloride
take 0.5g of this product, add water 48ml/heat and dissolve, cool, add 2ml nitric acid, shake, divide the solution into two equal parts, separate into 50ml Nessler colorimetric tube, add 1ml of silver nitrate test solution to one portion, place it for 10 minutes, filter it repeatedly with filter paper until the filtrate is completely clarified, add 7.5ml of standard sodium solution for gasification and an appropriate amount of water to make it 50ml, shake it well, as a control solution, it was placed in the dark for 5 minutes. In the other part, add 1ml of silver nitrate test solution and water to 50ml, shake well, and place in the dark for 5 minutes. If it is turbid, it should not be more concentrated (0.03%) than the control solution.
sulfate
take 2.0g of this product, add 50ml of water, heat and dissolve in water bath, cool, add 4ml of dilute hydrochloric acid, repeatedly filter until the solution is clear, the filtrate is divided into two equal parts, and place 50ml of Nessler's colorimetric tube, add 5ml of 25% barium chloride solution in one portion, shake well, place for 10 minutes, if turbid, filter repeatedly until the filtrate is clear, then add 5.0ml of standard potassium sulfate solution and appropriate amount of water to make 50ml, shake well, for 10 minutes, as a control solution. In the other portion, add 5ml of 25% barium chloride solution and an appropriate amount of water to 50ml, shake well, and place for 10 minutes. If it is turbid, compared with the control solution, it should not be more JT(0. 05).
loss on drying
take this product, with phosphorus pentoxide as desiccant, at 80°C under reduced pressure drying to constant weight, weight loss should not exceed 0.5% (General rule 0831).
