Sodium Chloride USP (US Pharmacopoeia)

NaCl -- 58.44
CAS 7647-14-5
Sodium Chloride contains not less than 99.0 percent and not more than 100.5 percent of NaCl, calculated on the dried basis.

Appearance of solution: Dissolve 20.0 g of the substance in carbon dioxide-free water, and dilute with the same solvent to 100.0 mL. This solution is clear and colorless.
Identification: It responds to the tests for Sodium and for Chloride.
Chloride: Dissolve about 3 mg of the substance in 2 mL of water. Acidify with diluted nitric acid and add 0.4 mL of silver nitrate TS. Shake, and allow to stand. A curdled, white precipitate is formed. Centrifuge, wash the precipitate with three 1-mL portions of water, and discard the washings. Carry out this operation rapidly in subdued light, disregarding the fact that the supernatant may not become perfectly clear. Suspend the precipitate in 2 mL of water and add 1.5 mL of 10 N ammonium hydroxide. The precipitate dissolves easily with the possible exception of a few large particles, which dissolve more slowly.
Bacterial endotoxins: The level of Bacterial endotoxins are such that the requirement under the relevant dosage form monograph (s) in which the substance is used can be met.
Sterility: Where the label states that the substance is sterile, it meets the requirements for Sterility under the relevant dosage form monograph (s) in which the substance is used.
Acidity or alkalinity: To 20 mL of the solution prepared for the test for Appearance of solution, add 0.1 mL of bromothymol blue TS: not more than 0.5 mL of 0.01 N hydrochloric acid or 0.01 N sodium hydroxide is required to change the color of this solution.
Loss on drying: Dry the test material at 105C for 2 hours: it loses not more than 0.5% of its weight, determined on a 1.000 g sample.
Limit of bromides: To 0.5 mL of the solution prepared for the test for Appearance of solution, add 4.0 mL of water, 2.0 mL of pH 4.7 phenol red TS, and 1.0 mL of chloramine T solution (0.1 mg per mL), and mix immediately. After 2 minutes, add 0.15 mL of 0.1 N sodium thiosulfate, mix, dilute with water to 10.0 mL, and mix. The absorbance of this solution measured at 590 nm, using water as the comparison liquid, is not greater than that of a Standard solution, concomitantly prepared, using 5.0 mL of a solution containing 3.0 mg of potassium bromide per L and proceeding as above, starting with the addition of 2.0 mL of pH 4.7 phenol red TS (0.010%).
Change to read:
Limit of phosphates:
Phosphate stock standard solution: Dissolve an accurately weighed quantity of monobasic potassium phosphate in water to obtain a solution having a concentration of about 0.716 mg per mL.

Standard solution: Dilute 2 mL of the Phosphate standard solution with water to 100 mL.
Test solution: Dilute 2 mL of the solution prepared in the test for Appearance of solution with water to 100 mL.
Procedure: To the Standard solution and the Test solution, add 4 mL of Sulfomolybdic acid solution, and add 0.1 mL of a mixture of 1 mL of stronger acid stannous chloride TS and 10 mL of 2 N hydrochloric acid. After 10 minutes, compare the colors of 20 mL of each solution: any color in the Test solution is not more intense than that in the Standard solution (0.0025%).
Sulfomolybdic acid solution: Dissolve with heating 2.5 g of ammonium molybdate in 20 mL of water. Dilute 28 mL of sulfuric acid with 50 mL of water, then cool. Mix the two solutions, and dilute with water to 100 mL. USP30

This solution contains the equivalent of 600 µg of potassium per mL. Dilute as required to obtain not fewer than three solutions at concentrations that span the expected value in the Test solution.
Procedure: Using atomic absorption spectrophotometry, measure, at least three times, the emission intensity of the Test solution and the Standard solution using an air acetylene flame and a wavelength of 766.5 nm.
