Levothyroxine EP Impurity C is a specified related substance listed in the European Pharmacopoeia for levothyroxine. It represents a minor degradation or synthetic impurity of the API, and its level must be controlled and measured using validated methods, such as HPLC, to ensure the purity, quality, and safety of levothyroxine products.
