in SPPS is very widespread for Fmoc/tBu approach, because its removal with piperidine solution does not disturb the acid-labile linker between the peptide and the resin. A typical SPPS Fmoc deprotection is performed with a solution of 20%

The Fmoc group is rapidly removed by base. Piperidine is usually preferred for Fmoc group removal as it forms a stable adduct with the dibenzofulvene byproduct, preventing it from reacting with the substrate.
