Niacinamide Properties
Item | Standard |
Appearance | White crystalline powder |
Solubility | Free soluble in water and in anhydrous ethanol, slightly soluble in methylene chloride |
Absorption coefficient | Add hydrochloric acid solution and dilute quantitatively. Measure at a wavelength of 261nm using UV visible spectrophotometry |
Identification chemical reaction | Add sodium hydroxide test solution and slowly heat it. The generated ammonia causes the moist red litmus test paper to change.Continue heat until the ammonia odor is completely removed,Cool down.Add phenolphthalein indicator solution, neutralize with dilute sulfuric acid, and add copper sulfate test solution to precipitate a light blue precipitate. |
Identification UV spectrum | There is maximum absorption at the wavelength of 261nm and minimum absorption at the wavelength of 245nm. The ratio of absorbance at the wavelength of 245nm to that at the wavelength of 261nm should be 0.63-0.67. |
Identification Infrared absorption spectrum | Comply |
Assay | ≥99.00% |
Melting point | 128.00-131.00℃ |
Appearance of Solution | Solution clarification colorless |
Related Substances | Comply |
