Advantage This grade of azelaic acid is obtained by further extraction and adsorption of pharmaceutical grade azelaic acid, which further reduces various impurities. All indicators are better than pharmaceutical grade azelaic acid. It can be used for quantitative control analysis of azelaic acid, with the highest content , the maximum impurity does not exceed 0.05%, and the content exceeds 99.5%. It can be used in organic synthesis as a downstream product of azelaic acid.
Use 2 This grade of azelaic acid has been washed and adsorbed, and the derivatives synthesized with this grade of azelaic acid have less impurities, good color and high light transmittance.
