Web4-(acetylamino)-5-chloro-2-methoxybenzoate, commonly referred to as “impurity B.” This unknown peak found in the impurity F working standard was determined not to be identical to EP impurity B due to differences in retention time; whereas, impurity B elutes at approximately 0.48 min. The origins of other impurities are still undetermined.
