Organic synthesis is a vast discipline that relies on a sophisticated toolkit of chemical building blocks to construct complex molecules. Among these, Fmoc-His(Boc)-OH·CHA (CAS: 210820-99-8) plays a significant role, particularly in the synthesis of peptides. NINGBO INNO PHARMCHEM CO.,LTD., a specialized supplier of fine chemicals, offers valuable insights into the chemical significance and applications of this compound in organic synthesis.

Fmoc-His(Boc)-OH·CHA is a derivative of L-histidine, a semi-essential amino acid with a reactive imidazole side chain. In organic synthesis, especially in solid-phase peptide synthesis (SPPS) employing the Fmoc strategy, the imidazole ring of histidine requires appropriate protection to prevent unwanted side reactions. The Fmoc (9-fluorenylmethyloxycarbonyl) group, attached to the alpha-amino group, is labile under basic conditions, facilitating its removal during the iterative coupling cycles. The tert-butyloxycarbonyl (Boc) group, appended to the imidazole nitrogen, provides robust protection that can withstand the basic conditions used for Fmoc deprotection but is selectively removed under acidic conditions at the end of the synthesis.

The cyclohexylamine (CHA) salt form of Fmoc-His(Boc)-OH·CHA is a strategic choice for organic chemists. This salt formation often improves the crystallinity, stability, and solubility of the compound in organic solvents commonly used in synthesis. This enhances the ease of handling and incorporation into reaction mixtures, leading to more efficient and predictable coupling reactions. For researchers engaged in complex organic synthesis projects, having access to well-characterized and stable building blocks like this is paramount.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying Fmoc-His(Boc)-OH·CHA that meets high purity standards, which is essential for achieving high-fidelity synthesis.
