Application

Piperidine can be used as:
  • A Fmoc removal agent in solid-phase peptide synthesis.
  • An organic structure-directing agent in the synthesis of ferrierite zeolites and CoAPO (cobalt aluminophosphate) materials.
  • A reagent in the preparation of N-(2,4-dinitrophenyl)piperidine by reacting with 2,4-dinitrochlorobenzene via aromatic nucleophilic substitution reaction.
