Specification:1g
Description:Disodium phosphonomycin is a white crystalline powder. Odorless, salty; It deliquesces easily in air. Soluble in water, slightly soluble in methanol, almost insoluble in ethanol or ether.
Take Disodium phosphonomycin and precision said, adding water to dissolve and quantitative dilution made each 1 ml contains about 50 mg of solution, in accordance with the determination of 2 (2010 edition pharmacopoeia appendix Ⅵ E), than the curl is 4.2 ° and 5.5 °.
Take about 11mg of Disodium phosphoycin, add 2ml of water, shake it, add 1ml of perchloric acid and 2ml of 0.1mol/L sodium perchlorate solution, heat it in water bath for 10 minutes, add 1ml of ammonium molybdate test solution and 1ml of 1-amino-2 naphtho-4 sulfonic acid test solution while hot, shake it well, and the solution will show blue color.
Disodium phosphonomycin was added with water to make a solution containing 50mg per 1ml, and the pH value should be 9.0 ~ 10.5 according to law.
Melting point:>300 °C
Chemical property:white crystalline powder.
Use:Used in infection caused by Staphylococcus aureus,colon bacillus and Proteus.
