Determination of para-aminobenzoic acid, a degradation product of procaine hydrochloride, by zero-crossing first-derivative spectrometry
A first derivative spectrometric method has been developed for the determination of the para-aminobenzoic acid (PABA), a related substance and degradation product of the local anesthetic procaine hydrochloride (PH). The wavelength selected for the determination of para-aminobenzoic acid in the prese...
