L,L-Dityrosine dihydrochloride has found utility as a crosslinking agent to enhance the stability of proteins and peptides. Similarly, in materials science, it has been employed as a fundamental component for synthesizing novel materials endowed with exceptional properties. The mechanism of action is believed to involve the covalent bonding between two tyrosine residues, leading to the formation of a dimeric structure that surpasses the stability of individual tyrosine residues. Importantly, the formation of L,L-Dityrosine dihydrochloride has been observed to rely on the presence of reactive oxygen species, such as hydrogen peroxide or superoxide.
