Boc-β-Ala-OH is widely used in peptide synthesis as a protecting group for the amino acid β-alanine. The Boc (tert-butyloxycarbonyl) group shields the amine functionality during the coupling reactions, ensuring selective and efficient peptide chain elongation. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps prevent unwanted side reactions and maintains the integrity of the peptide sequence. After the synthesis is complete, the Boc group can be easily removed under acidic conditions, allowing for further modifications or deprotection steps. Its stability and compatibility with various reagents make it a preferred choice in the preparation of complex peptides and bioactive molecules. Additionally, Boc-β-Ala-OH is utilized in the development of peptidomimetics and drug candidates, where β-alanine serves as a key building block to enhance stability, solubility, or biological activity.
