IDENTIFICATION A. Standard: 0.5 g of USP Propylparaben Sample: 0.5 g Analysis: Dissolve the Sample in 5 mL of water. Acidify with hydrochloric acid and filter the resulting precipitate. Wash the precipitate with water, and dry over silica gel for 5 h. Repeat with the Standard. Acceptance criteria: The IR absorption spectrum of a mineral oil dispersion of the Sample exhibits maxima only at the same wavelengths as those of a mineral oil dispersion of the Standard. B. Sample solution: Ignite 0.3 g of Propylparaben Sodium, cool, and dissolve the residue in 3 mL of 3 N hydrochloric acid. Acceptance criteria: A platinum wire dipped in the Sample solution imparts an intense, persistent yellow color to a nonluminous flame. Related Compounds: To pass the test by chromatography. Chloride and Sulfate, Chloride: To pass the test. --- 0.035%. Chloride and Sulfate, Sulfate: To pass the test --- 0.12%. pH: Sample solution: 1 mg/Ml Acceptance criteria: 9.5 to 10.5 Water Determination: NMT 5.0% Completeness of Solution: Sample solution: Dissolve 1 g in water. Acceptance criteria: Meets the requirements Specifications of Sodium Propyl Hydroxybenzoate BP Ph Eur Grade Sodium Propylparaben Sodium Propyl Parahydroxybenzoate, Ph Eur C10H11NaO3 --- 202.2 --- CAS 35285-69-9 Action and use: Antimicrobial preservative. DEFINITION Sodium propyl parahydroxybenzoate contains not less than 99.0 per cent and not more than the equivalent of 104.0 per cent of sodium 4-(propoxycarbonyl)phenolate, calculated with reference to the anhydrous substance. CHARACTERS A white or almost white, crystalline powder, freely soluble in water, sparingly soluble in alcohol, practically insoluble in methylene chloride. IDENTIFICATION First identification A, B, E. Second identification A, C, D, E. A. Dissolve 0.5 g in 50 ml of water. Immediately add 5 ml of hydrochloric acid. Filter, and wash the precipitate with water. Dry at 80C in vacuo for 2 h. The melting point of the precipitate is 96C to 99C. B. Examine the precipitate obtained in identification test A by infrared absorption spectrophotometry, comparing with the spectrum obtained with propyl parahydroxybenzoate CRS. C. Examine the chromatograms obtained in the test for related substances. The principal spot in the chromatogram obtained with test solution (b) is similar in position and size to the principal spot in the chromatogram obtained with reference solution (c). D. To about 10 mg in a test-tube add 1 ml of sodium carbonate solution, boil for 30 s and cool. Add 5 ml of aminopyrazolone solution and 1 ml of potassium ferricyanide solution and mix. An orange to red colour develops. E. To 1 ml of solution S (see Tests) add 1 ml of water. The solution gives reaction (a) of sodium. TESTS Solution S: Dissolve 5.0 g in carbon dioxide-free water prepared from distilled water, and dilute to 50 ml with the same solvent. Appearance of solution: Solution S, examined immediately after preparation, is clear and not more intensely coloured than reference solution. pH: Dilute 1 ml of solution S to 100 ml with carbon dioxide-free water. The pH of the solution is 9.5 to 10.5. Related substances: To pass the test. Chlorides: To 10 ml of solution S add 30 ml of water and 1 ml of nitric acid and dilute to 50 ml with water. Shake and filter. Dilute 10 ml of the filtrate to 15 ml with water. The solution complies with the limit test for chlorides (350 ppm). Prepare the standard using 14 ml of chloride standard solution (5 ppm Cl) to which 1 ml of water has been added. Sulphates: To 25 ml of solution S add 5 ml of distilled water and 10 ml of hydrochloric acid and dilute to 50 ml with distilled water. Shake and filter. Dilute 10 ml of the filtrate to 15 ml with distilled water. The solution complies with the limit test for sulphates (300 ppm). Heavy metals: 2.0 g complies with limit test C for heavy metals (10 ppm). Prepare the standard using 2 ml of lead standard solution (10 ppm Pb). Water: Not more than 5.0 per cent, determined on 0.500 g by the semi-micro determination of water.
