Boc-L-2,4-Diaminobutyric acid (N-Boc-L-2,4-diaminobutyric acid; Boc-Dab-OH) is a versatile synthetic starting material with a cleavable protecting group. Boc-L-2,4-Diaminobutyric acid not only reduces the backbone cleavage rate by protecting the side-chain γ-amino group, but also triggers intramolecular cyclization of self-immolative linkers under acidic cleavage conditions, thus constructing stimuli-responsive materials. Boc-L-2,4-Diaminobutyric acid is also an important building block for bioactive molecules. It can be used in the synthesis of ASCT2 (SLC1A5) inhibitors and carboxynorspermine, and can also serve as an internal standard to support the quantitative detection of specific intracellular amino acids by UPLC-QQQ-MS .
