摘要:

A new bromometric assay procedure for penicillins was developed, using an organic brominating agent. 1,3-Dibromo, 5,5-dimethylhydantion (DBH). The experimental conditions, the molar ratio as well as the identification of the reaction products were thoroughly studied. The end point could be detected visually or potentiometrically. Spectrophotometric titration could also be performed. The suggested procedure could be successfully applied to pharmaceutical preparations containing penicillins. The percentage recoveries for different penicillins were satisfactory.
