title: High-performance liquid chromatographic assay for benzocaine and p-aminobenzoic acid including preliminary stability data.
abstract: A high-performance liquid chromatographic assay was developed that separates and quantitates benzocaine and its primary degradation product, p-aminobenzoic acid. This method is rapid, sensitive, and specific. Preliminary stability data obtained with this method demonstrate its utility for this purpose.
