Chemical Identity and Properties

Boc-(R)-3-Amino-4-(3,4-difluorophenyl)butyric acid is an N-protected, chiral amino acid derivative. Its molecular formula is C15H19F2NO4, and it has a molecular weight of approximately 315.31 g/mol. The compound typically presents as a white to off-white solid or powder, with a reported purity of 97% or higher by HPLC. Key structural elements contributing to its utility include:

• The Boc Protecting Group: The tert-butyloxycarbonyl (Boc) group is attached to the amine nitrogen, serving as a protecting group that can be selectively removed under mild acidic conditions. This is fundamental for controlled synthesis in peptide chemistry and organic transformations.
• Chirality: The designation (R) indicates a specific stereochemical configuration at the alpha-carbon (or the relevant chiral center in this derivative). Chirality is critical in pharmaceuticals as enantiomers often exhibit vastly different biological activities and safety profiles.
• The 3,4-Difluorophenyl Moiety: The presence of two fluorine atoms on the phenyl ring significantly influences the electronic properties and lipophilicity of the molecule. This fluorination often enhances metabolic stability, alters binding affinities, and can improve the pharmacokinetic properties of the final drug product.

These properties make it an invaluable building block for creating complex molecules with tailored biological and chemical characteristics.

Key Applications in Research and Development

The versatility of Boc-(R)-3-Amino-4-(3,4-difluorophenyl)butyric acid makes it a sought-after intermediate across several scientific disciplines:

• Peptide Synthesis: It is a critical component in the synthesis of peptides, especially those requiring specific structural modifications or enhanced stability due to the fluorinated phenyl group. Its Boc protection allows for its incorporation into peptide chains using standard solid-phase or solution-phase methodologies.
• Pharmaceutical Intermediate: This compound serves as a key chiral building block for the synthesis of various active pharmaceutical ingredients (APIs). Its unique structural features make it suitable for incorporation into molecules targeting a wide range of diseases, particularly those where fluorine substitution is known to improve efficacy or pharmacokinetics.
• Drug Discovery: Researchers utilize this intermediate to explore novel chemical entities and optimize lead compounds. The ability to precisely incorporate a chiral, fluorinated amino acid derivative allows for the systematic investigation of structure-activity relationships (SAR).
