Chemical Structure



Boc-His(Bzl)-OH is a commonly used building block in chemical synthesis, particularly in peptide synthesis. It serves as a protected form of histidine, a versatile amino acid with both acidic and basic properties. The Boc (tert-butoxycarbonyl) protecting group on the amino terminus of histidine provides stability to the molecule during chemical reactions, allowing for selective manipulation of other functional groups without affecting the histidine residue. This enables chemists to control the sequence of amino acids in a peptide chain and ultimately determine the structure and function of the resulting peptide. Boc-His(Bzl)-OH is utilized in the synthesis of various peptide-based pharmaceuticals, research chemicals, and bioconjugates, making it an essential tool in the field of organic chemistry.
