abstract：:A modified NF method for the quantitative determination of pentaerythritol tetranitrate is reported. A solution of powder is made directly from the dosage form in glacial acetic acid and is then reacted with phenoldisulfonic acid TS. The proposed method saves approximately 75% of the time required with the NF method. ...
