1 | Description | White to creamy-white, crystalline powder, odorless to having a slight odor |
2 | Solubility | Freely soluble in 30% ammonium solution; slightly soluble in acetone; practically insoluble in alcohol, in chloroform and in ether. Decomposes in moderately strong mineral acids. |
3 | Identification – By IR – By HPLC – By Chemically |
The IR absorption spectrum of the test preparation should exhibit maxima at the same wavelength as that of a similar preparation of Silver Sulfadiazine working standard. The principal peak in the chromatogram obtained with test solution should correspond to the peak in the chromatogram obtained with standard. Meets the requirements. |
