This compound is primarily used in peptide synthesis as a building block for creating specific peptide sequences. Its structure, featuring a nitro group on the phenyl ring, makes it valuable for introducing aromatic and electron-withdrawing properties into peptides, which can influence their stability and interactions. It is often employed in research to study peptide conformation, receptor binding, and enzyme activity. Additionally, it serves as an intermediate in the development of pharmaceuticals, particularly in the design of peptide-based drugs targeting various diseases. Its water of hydration ensures stability during storage and handling.
