Witrynaspreadsheet) of the data is recommended. Impurities should be designated by code number or by an appropriate descriptor, e.g., retention time. If a higher reporting threshold is proposed, it should be fully justified. All impurities at a level greater than (>) the reporting threshold should be summed and reported as total impurities. WitrynaWhat would be an appropriate strategy to qualify a new impurity that arises during Phase III or with a commercial product? For example, would it be acceptable that a new unidentified impurity, discovered at the 0.05-0.09% range requires no action to be taken? Would an impurity discovered in the 0.10 to 0.15%, even if it triggers a structural
