Advantages: This grade of Azelaic acid is obtained by further extraction and adsorption of pharmaceutical grade Azelaic acid, which further reduces various impurities. The indicators are better than pharmaceutical grade Azelaic acid, which can be used for quantitative control analysis of Azelaic acid. Impurities do not exceed 0.05%, and the Content exceeds 99.5%, which can be used in organic synthesis as downstream products of Azelaic acid.
Main Uses: This grade of Azelaic acid is subjected to washing and adsorption treatment. Derivatives synthesized with this grade of Azelaic acid have fewer impurities, good color and luster, and high light transmittance.
