The Apixaban Chloro Ester Impurity is a process-related impurity that can form during the synthesis of Apixaban. It arises when a chloro-substituted ester group is incorporated into an intermediate instead of the intended functional group, typically due to side reactions in esterification or halogenation steps. This impurity must be strictly controlled, as it can impact the purity, safety, and efficacy of the final drug product.
