The field of peptide synthesis has been revolutionized by the strategic use of protected amino acids, and Boc-amino acids, in particular, have become indispensable tools. Among these, N-alpha, N-im-bis-Boc-L-histidine, often abbreviated as Boc-His(Boc)-OH, plays a pivotal role due to the unique chemical properties of histidine. Understanding the function and sourcing of this compound is essential for anyone involved in peptide chemistry.

Histidine is a unique amino acid with an imidazole ring, which can act as both a nucleophile and a proton donor, making it highly reactive. In peptide synthesis, this reactivity can lead to unwanted side reactions, such as acylation of the imidazole nitrogen or participation in cyclization reactions. To prevent these complications and ensure precise peptide chain elongation, protecting groups are employed. The tert-butoxycarbonyl (Boc) group is a widely used N-alpha protecting group, and in Boc-His(Boc)-OH, it is also strategically placed on the imidazole nitrogen. This dual protection strategy effectively shields the reactive sites of histidine, allowing for its controlled incorporation into the growing peptide chain during both solid-phase and solution-phase synthesis.

For researchers and manufacturers, sourcing high-quality Boc-His(Boc)-OH is paramount. The compound is typically identified by its CAS number 20866-46-0. When considering where to buy Boc-His(Boc)-OH, it is important to look for suppliers that offer high purity and consistent quality, as even minor impurities can compromise the success of a complex peptide synthesis. Many companies offer these critical peptide synthesis reagents, and NINGBO INNO PHARMCHEM CO.,LTD. is a notable supplier in this domain.
