H-Arg(Tos)-OH

Description:
H-Arg(Tos)-OH, also known as Tosyl-L-arginine, is a derivative of the amino acid arginine where the amino group is protected by a tosyl (p-toluenesulfonyl) group. This modification enhances the stability and solubility of the compound, making it useful in peptide synthesis and other chemical applications. The tosyl group is a common protecting group in organic synthesis, allowing for selective reactions without interference from the amino group. H-Arg(Tos)-OH is typically a white to off-white crystalline solid and is soluble in polar solvents such as water and methanol. It is often utilized in the synthesis of peptides and other bioactive molecules due to its ability to facilitate the introduction of arginine residues into larger structures. The compound is also of interest in biochemical research, particularly in studies involving protein interactions and modifications. As with many chemical substances, proper handling and safety precautions should be observed, as it may pose risks if ingested or improperly managed.
