Application

  • Stability-indicating electrochemical methods for the determination of meclophenoxate hydrochloride and pyritinol dihydrochloride using ion-selective membrane electrodes.: This study by El-Bardicy et al. explores the use of sodium tetraphenyl borate in ion-selective membrane electrodes to determine the stability of meclophenoxate hydrochloride and pyritinol dihydrochloride. The method is noted for its accuracy and reliability in pharmaceutical analysis (El-Bardicy et al., 2007).
  • Amodiaquine polymeric membrane electrode.: Malongo et al. developed a polymeric membrane electrode incorporating sodium tetraphenyl borate for the determination of amodiaquine. This analytical method demonstrated high sensitivity and specificity, making it valuable for pharmaceutical applications (Malongo et al., 2006).
