title: N-bromosuccinimide assay of penicillins and cephalosporins.
abstract: All penicillins and cephalosporins known to possess biological activity respond to an N-bromosuccinimide assay. The developed method is not yet usable for determining stability, but it is useful as a bulk or batching assay.
