Medchemexpress LLC 6-heptenoic acid, 2-[[(9H-fluoren-9-ylmethoxy)carbonyl]amino]-2-methyl-, (2R)- | 288617-77-6 | MFCD09879889 | 98.8% | 379.45 | C23H25NO4 | 1 G

Fmoc-(R)-2-(pentenyl)Ala-OH is an Fmoc-protected, chiral alkenyl amino acid used as a building block in peptide synthesis. It provides an (R)-configured 2-(pentenyl) side chain that can be incorporated into peptides during solid-phase or solution-phase synthesis and subsequently modified by alkenyl-selective reactions such as ring-closing metathesis to produce stapled peptides or other constrained analogs.

Fmoc-protected for compatibility with standard Fmoc solid-phase peptide synthesis.
Chiral (R) configuration for stereospecific incorporation.
Alkenyl side chain suitable for ring-closing metathesis and other transformations.
Applicable to both solid-phase and solution-phase peptide assembly.
High purity to support consistent coupling and analytical characterization.
Available in laboratory-scale pack sizes for research applications.
