NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying high-quality chemical intermediates for scientific advancement. This article highlights Fmoc-Lys-OH HCl (CAS 139262-23-0), a fundamental protected amino acid derivative whose chemical properties are key to developing advanced peptide therapeutics and sophisticated research tools.

Fmoc-Lys-OH HCl is an essential reagent in the field of peptide synthesis, particularly within the widely adopted solid-phase peptide synthesis (SPPS) methodology. The core of its utility lies in the Fmoc (9-fluorenylmethoxycarbonyl) protecting group. This group offers a mild, base-labile method for protecting the alpha-amino group of the lysine residue. This is crucial because it allows for selective deprotection and subsequent peptide bond formation without damaging the growing peptide chain or other functional groups. The orthogonality of the Fmoc strategy, where the alpha-amino protecting group is removed under basic conditions while side-chain protecting groups are typically removed under acidic conditions, allows for precise control over the synthesis process. The ease of accessing high-purity Fmoc-Lys-OH HCl from suppliers like NINGBO INNO PHARMCHEM CO.,LTD. underpins its widespread use.

The chemical structure of Fmoc-Lys-OH HCl offers significant advantages for downstream modifications. Lysine, an essential amino acid, contains a side chain with a terminal epsilon-amino group. This amino group, once the Fmoc protection on the alpha-amino group is removed, becomes available for various chemical reactions. This makes Fmoc-Lys-OH HCl an ideal building block for creating peptide conjugates. For example, in the development of peptide therapeutics, this lysine side chain can be modified to improve drug efficacy, prolong circulation time, or target specific tissues. The ability to readily incorporate and then functionalize lysine residues allows for the creation of highly tailored peptide drugs.

The utility of Fmoc-Lys-OH HCl extends to the creation of innovative research tools. For instance, it is used in the synthesis of peptides for bioconjugation, where peptides are linked to reporter molecules like fluorescent dyes or affinity tags for biological imaging and detection. It also plays a role in creating peptide-based vaccines, where lysine residues can serve as attachment points for antigens or adjuvants. The consistent quality and purity of Fmoc-Lys-OH HCl from NINGBO INNO PHARMCHEM CO.,LTD. are vital for the reproducibility and success of these complex experimental designs. Researchers can confidently buy Fmoc-Lys-OH HCl knowing it meets the high standards required for advanced biochemical and pharmaceutical applications.
