4-Azido-L-phenylalanine hydrochloride

4-Azido-L-phenylalanine (pAzF), an unnatural amino acid featuring a bioorthogonal azide handle, is site-specifically incorporated into proteins via genetic code expansion, providing a unique modification site. This incorporated azide enables precise attachment of probes (dyes, tags, therapeutics) through bioorthogonal click chemistry or photo-crosslinking, yielding proteins with novel functionalities for imaging, interaction studies, and creating biomaterials/bioconjugates. Consequently, 4-Azido-L-phenylalanine (pAzF) is a powerful tool in chemical biology and biotechnology for protein engineering, functional analysis, and therapeutic applications across diverse cellular systems.
