title: Stability-indicating method for determination of some acid-stable penicillins.
abstract: A proposed titrimetric procedure for determining some acid-stable penicillins is investigated. The procedure has been used for both pure substances and dosage forms and was fairly accurate. A study of the mechanism of the reaction of the suggested stability-indicating method is presented.
