CAS 98897-09-7: D-Glucopyranose,6-[(4-azido-2-hydroxybenzoyl)amino]-6-deoxy-

6-(4-Azido-2-hydroxybenzamido)-6-deoxy-D-glucopyranose (AGB) is a potential photoaffinity label that can be used to identify and characterize the transporter. The photoaffinity label is synthesized by reacting 2,4-dinitrophenylhydrazine with 6-(4-azido-2-hydroxybenzamido)-6-deoxy-D-glucopyranose in the presence of sodium bicarbonate or potassium carbonate. The photolysis of AGB produces an azide radical cation that reacts with amino acid residues on the protein surface, forming a covalent bond. This labeling process is irreversible.
