The synthesis of complex peptides is a cornerstone of modern pharmaceutical research and development. At the heart of this process lie protected amino acid derivatives, each meticulously designed to facilitate controlled chain elongation. Fmoc-His(Boc)-OH·CHA, identified by CAS number 210820-99-8, is a prime example of such a critical reagent, enabling the accurate incorporation of histidine into growing peptide chains. Understanding its chemistry is key to leveraging its full potential.

The molecular structure of Fmoc-His(Boc)-OH·CHA (C32H40N4O6) features the histidine amino acid backbone, with two crucial protecting groups. The N-alpha position, which participates in peptide bond formation, is protected by the Fmoc (9-fluorenylmethyloxycarbonyl) group. This group is base-labile, allowing for selective removal under mild conditions during SPPS. Simultaneously, the imidazole ring of the histidine side chain is protected by a Boc (tert-butyloxycarbonyl) group. This acid-labile protecting group prevents unwanted side reactions of the imidazole nitrogen during Fmoc deprotection or coupling steps.

The synthesis of Fmoc-His(Boc)-OH·CHA typically involves a multi-step process starting from L-histidine. First, the imidazole ring is protected with the Boc group, often using di-tert-butyl dicarbonate. Subsequently, the alpha-amino group is derivatized with the Fmoc group, commonly using Fmoc-Cl or Fmoc-OSu. The final step often involves the formation of a salt, such as the cyclohexylamine salt, which improves the compound's crystallinity, stability, and handling characteristics, making it a more practical reagent for laboratory use. Researchers looking to buy Fmoc-His(Boc)-OH CHA benefit from these optimized preparation methods which yield high-purity products.

The primary application of Fmoc-His(Boc)-OH·CHA is in Fmoc-based solid-phase peptide synthesis. It is coupled to the C-terminus of a growing peptide chain, and after deprotection of the Fmoc group, the next Fmoc-protected amino acid is added. This iterative process allows for the construction of peptides with defined sequences and high fidelity. The reliability of this process hinges on the quality of the reagents used. Therefore, sourcing from a reputable Fmoc-His(Boc)-OH manufacturer China ensures consistent product performance.

For those in the pharmaceutical industry, obtaining this intermediate is crucial for drug discovery and development. Peptides containing histidine are prevalent in many biologically active molecules, including hormones, enzymes, and signaling peptides. Efficiently synthesizing these peptides requires a dependable supply of high-quality CAS 210820-99-8 supplier. Understanding the chemical properties and synthesis pathways of Fmoc-His(Boc)-OH·CHA empowers researchers and procurement specialists to make informed decisions when placing orders.

In conclusion, the chemistry behind Fmoc-His(Boc)-OH·CHA is designed for precision in peptide synthesis. Its dual protection strategy and stable salt form make it an invaluable tool for researchers. When you need to purchase this essential building block, remember that quality and reliability are paramount. Partnering with experienced chemical suppliers ensures that your research objectives can be met effectively and efficiently.
