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.
