Fmoc-Asp(2-phenylisopropyl ester)-OH

Catalog No：GA21534-1g CAS No.：200336-86-3 MDLNo： Brand:Glpbio purity： 特性： Purpose:An aspartic acid derivative allowing specific side chain deprotection with 1% TFA in dichloromethane. Ocampo et al. applied OPp protection during the synthesis of a peptide-oligonucleotide conjugate and cleaved it with 3% trichloroacetic acid in DCM. The OPp derivative is far less prone towards base-catalyzed aspartimide formation than the OAll, OBzl, or ODmab esters, its stability comes close to the stability of the OtBu ester.Soluble in DMSO
