Used primarily in biochemical research, this compound serves as a modified amino acid to study enzyme interactions and protein behavior. It is particularly valuable in investigations related to tyrosine phosphorylation and nitrotyrosine formation, which are critical in understanding cellular signaling pathways and oxidative stress mechanisms. Additionally, it aids in the development of assays to detect and quantify nitrotyrosine in biological samples, contributing to research on diseases associated with oxidative damage, such as neurodegenerative disorders and cardiovascular conditions. Its unique structure also makes it a useful intermediate in synthesizing more complex molecules for pharmaceutical and biochemical studies.
