Description

Lys-Lys-Oh 3Tfa CAS NO 1423017-94-0 is a trifluoroacetic acid (TFA) salt derivative of the dipeptide lysyl-lysine. This compound is a crucial protected intermediate in solid-phase peptide synthesis (SPPS), offering enhanced solubility and stability for complex peptide chain assembly. It is primarily required by research institutions and pharmaceutical companies engaged in the development of therapeutic peptides, diagnostic agents, and biochemical tools.

Application

• Solid-Phase Peptide Synthesis (SPPS): A key protected building block for the sequential assembly of lysine-rich peptide sequences.
• Pharmaceutical Research: Intermediate in the synthesis of novel peptide-based drug candidates, including antimicrobial peptides (AMPs) and hormone analogs.
• Bioconjugation: Serves as a precursor for introducing reactive amine handles or cross-linking sites into larger biomolecules.
• Biochemical Tool Development: Used in the preparation of enzyme substrates, inhibitors, or affinity tags for proteomics and molecular biology studies.
• Material Science: Potential monomer for creating bio-inspired, peptide-functionalized polymers and surfaces.
