L-Histidine benzyl ester bistosylate（Cat No.:I044583）is a protected derivative of the amino acid L-histidine, commonly used in peptide synthesis and medicinal chemistry. Featuring a benzyl ester on the carboxyl group and two tosylate (p-toluenesulfonate) counterions, this compound offers enhanced solubility and reactivity for coupling reactions. It preserves the imidazole functionality of histidine, enabling selective modifications or incorporation into complex peptide sequences. L-Histidine benzyl ester bistosylate is particularly valuable in the synthesis of modified peptides, peptidomimetics, and histidine-containing bioactive molecules for biochemical and pharmaceutical research applications.
