Custom peptide synthesis is a cornerstone of modern drug discovery and biochemical research. Central to this process are high-quality amino acid derivatives, such as Fmoc-alpha-methylalanine (Fmoc-Aib-OH), identified by CAS 94744-50-0. As a specialized amino acid derivative, Fmoc-Aib-OH offers unique advantages that researchers actively seek when designing peptides with specific properties. This article explores the role of Fmoc-Aib-OH in custom peptide synthesis and guides you on how to effectively source it.

Why Choose Fmoc-Aib-OH for Custom Peptides?

Fmoc-Aib-OH is a derivative of alpha-aminoisobutyric acid, which itself is a non-proteinogenic amino acid. The key feature of Aib is the presence of two methyl groups on the alpha-carbon. When this is protected with the Fmoc group, it becomes a versatile building block for peptide synthesis:

  • Enhanced Stability: The alpha-methyl substitution imparts steric hindrance, which protects the peptide backbone from proteolytic enzymes. This leads to peptides with increased resistance to degradation and longer biological half-lives, a critical factor for therapeutic peptides.
  • Conformational Control: Alpha-methylated amino acids like Aib often favor specific secondary structures, such as helices. This can be strategically used to pre-organize peptides for optimal receptor binding or to impart desired structural characteristics.
  • Improved Solubility and Delivery: In some cases, the introduction of Aib residues can modify peptide solubility and membrane permeability, potentially improving drug delivery and absorption.

The Importance of Sourcing from a Reliable Manufacturer and Supplier

When undertaking custom peptide synthesis, the quality of the starting materials directly influences the success of the final product. Therefore, securing high-purity Fmoc-Aib-OH (≥98%) from a reputable manufacturer is essential. For procurement professionals, understanding the capabilities of potential suppliers is crucial:

  • Quality Control: A trusted supplier will provide comprehensive Certificates of Analysis (CoA) for each batch, confirming purity and identity.
  • Consistent Supply: Ensuring a stable and consistent supply of Fmoc-Aib-OH is vital for ongoing research or production. Partnering with a manufacturer that has robust production capacity is key.
  • Technical Support: Access to technical information and support from the manufacturer can aid in optimizing synthesis protocols and troubleshooting any issues.
  • Competitive Price: While quality is paramount, seeking competitive price points for bulk orders is a standard practice for procurement managers.

Where to Buy Fmoc-Aib-OH: The Chinese Advantage
