Product Technical Details

Product Overview

Fmoc-D-Ala-OH, chemically designated as (2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)propanoic acid, is a high-value chiral amino acid derivative widely employed in the synthesis of complex peptides and peptidomimetics. As a D-configured alanine building block protected with the fluorenylmethyloxycarbonyl (Fmoc) group, it enables orthogonal deprotection strategies in modern solid-phase peptide synthesis (SPPS). This intermediate ensures excellent stereochemical integrity and coupling efficiency, making it indispensable in the development of therapeutic peptides, diagnostic agents, and advanced research compounds.

Quality Assurance

Our Fmoc-D-Ala-OH meets stringent quality benchmarks essential for pharmaceutical applications:

  • Purity (HPLC): ≥98.5% (Typical: 99.54%)
  • Chiral Purity: ≥99.0% (Typical: 99.92%)
  • Water Content: ≤6.0% (Typical: 3.5%)
  • Conforms to internal factory standards for use in regulated environments

Industrial Applications

Primarily utilized as a specialty intermediate in peptide chemistry, Fmoc-D-Ala-OH supports the construction of stereochemically defined sequences in:

  • Solid-phase and solution-phase peptide synthesis
  • Development of enzyme-resistant peptide therapeutics
  • Preparation of chiral scaffolds for medicinal chemistry
  • Academic and industrial research requiring enantiomerically pure D-amino acid units

As a foundational building block rather than a direct active ingredient, it plays a critical role in upstream synthesis workflows but is not intended for direct formulation into final consumer products.
