Boc-beta-tert-butyl-L-alanine (CAS 79777-82-5) is supplied as a Protected amino-acid / peptidomimetic building block. In research synthesis, it is most relevant to peptide, peptidomimetic and medicinal-chemistry synthesis and a noncanonical or specially protected residue used to expand peptide and small-molecule chemical space.
Use when the target structure specifically requires this residue or protection pattern; confirm stereochemistry and deprotection compatibility before substituting it into an established route. Its value is route-specific, so selection should follow the intended transformation rather than the broad category label.

Application in Peptide and Peptidomimetic Design
Boc-beta-tert-butyl-L-alanine expands accessible chemical space through a noncanonical or specially protected residue used to expand peptide and small-molecule chemical space. This makes the product most relevant to sequence-defined SAR, conformational studies or specialized synthetic targets.
What to Check Before Incorporation
Confirm stereochemistry, free versus protected functional groups and the planned cleavage sequence. These details affect activation choice, solubility and the identity of the final residue.
Procurement Relevance
Use CAS 79777-82-5 together with the full product name when comparing suppliers. Similar shorthand names can refer to different positional isomers or protection states.
Additional chemistry is available in the specialty amino acid set. For synthesis planning beyond the building block, see specialty SPPS building blocks.
