Fmoc-β-Ala-Leu-OH LPPS Fmoc Derivatives Impurity HPLC 99+

1. Solid-Phase Peptide Synthesis (SPPS)
Widely used in Solid-Phase Peptide Synthesis as a pre-assembled β-Ala–Leu dipeptide building block.

• Fmoc group provides N-terminal protection
• C-terminal –COOH enables further peptide elongation
• Reduces coupling steps and improves synthesis efficiency

2. Introduction of Hydrophobic Residues
Leucine (Leu) is a hydrophobic amino acid that can:

• enhance peptide hydrophobicity
• influence secondary structure formation
• improve peptide–membrane interactions

Commonly used in:

• bioactive peptides
• receptor-binding peptides
• functional peptide sequences

3. Flexible Spacer Function (β-Ala)
The β-alanine residue serves as a flexible spacer.

Benefits include:

• increased backbone flexibility
• reduced steric hindrance
• optimized spatial arrangement of functional residues

Useful in:

• linker design
• peptide conjugates
• sequence optimization

4. Functional Peptide and Research Applications
Fmoc-β-Ala-Leu-OH is commonly used in the preparation of:

• functional peptides
• peptide analogs
• research peptides
• peptide libraries

The Leu residue contributes to hydrophobic interactions and conformational properties.
