A rapid method of qualitative identification of barbituric acids, which does not require prior isohtioil of the barbiturate from the pharmaceutical dosage forni, was developed utilizing mass spectrometry. This is achieved by the introduction o f a portion of the powdered preparation directly into th
produccs a curved segment a t lower pH values.8 In calculating the purity and ionization constant, only the linear portion of each plot was used. Nevertheless, it may be seen (Table 11) that the intercept obtained (and therefore the purity evaluated) is not markedly influenced by the choice of activ
