Applications of 81470-51-1
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Protecting group reagent for selective protection of the side-chain carboxyl groups of glutamic acid or aspartic acid in peptide synthesis | Introduced under basic conditions in solid-phase peptide synthesis (SPPS) to form a stable tert-butyl ester protecting group; removed subsequently via acidolysis (e.g., with TFA) |
| Peptide Chemistry | Synthesis of peptide fragments containing pyroglutamic acid | Condensed with amino components using Z-Pyr-OTBu to construct an N-terminal pyroglutamic acid residue, enabling mimicry of native bioactive peptides or enhancement of metabolic stability |
| Biochemical Research | Building block for enzyme inhibitors or receptor ligands | Used as a synthetic building block in solution-phase or solid-phase synthesis to develop small-molecule probes targeting specific proteases or neurotransmitter receptors |
