General description

Potassium phosphate tribasic exhibits high catalytic property in trans esterification reactions. It has bactericidal activity.

Application

Potassium phosphate tribasic has been used:
  • in lysis buffer for the isolation of protein from Gram positive bacteria
  • as a reagent for the scalable synthesis and post-modification of NU-1000 (mesoporous metal-organic framework)
  • as a reagent for the plasma membrane preparation of Lilium davidii or Oryza sativa with high purity
