Retinoic Acid Impurities and Synthesis

Impurities of Retinoic Acid are unintentional chemical compounds present during the manufacture or storage of retinoic acid, a vitamin A derivative frequently used in dermatology. They may form from raw materials, reagents, intermediates, or degradation products. Retinoic Acid impurities require strict control and monitoring to assure drug safety, efficacy, and quality, and analytical procedures help identify, quantify, and characterize these impurities.

Daicel Pharma provides a Certificate of Analysis (CoA) of Retinoic Acid impurity standards which include 4-Oxo-9-Cis Retinoic acid, 5,6-Epoxy-9-Cis-Retinoic Acid, and All-trans 5,6-Epoxy Retinoic Acid. Our cGMP-certified analytical facility provides a comprehensive CoA with detailed characterization data like 1H NMR, 13C NMR, IR, MASS, and HPLC purity. Additional characterizations like 13C-DEPT are available upon request.
