This paper presents a reevaluation of the synthesis and properties of Fmoc-His(3-Bum)-OH regarding its application in SPPS with minimal racemization of histidine residues during coupling and esterification reactions. By-product formation during the deprotection of the test peptides could be significantly reduced by scavenging the concomitantly formed HCHO, e.g. with methoxyamine.
