H-Tyr(tBu)-OEt;71890-58-9

Product Information (A097076)

Product Code：A097076
English Name：H-Tyr(tBu)-OEt
English Alias：(S)-ethyl 2-amino-3-(4-(tert-butoxy)phenyl)propanoate
CAS No.：71890-58-9
Molecular Formula：C₁₅H₂₃NO₃
Molecular Weight：265.35

Advantages

High Purity & Chiral Confirmation：HPLC ≥99.0%, configuration confirmed by NMR (with chiral shift reagents) and optical rotation, suitable for tyrosine derivative synthesis/analysis.
Excellent Stability：Stable for 36 months at 2-8℃ in sealed storage; tert-butoxy group resists hydrolysis under normal conditions.

Applications

Peptide Synthesis Intermediate：Used to prepare tyrosine derivatives with tert-butoxy protection, preventing amino/phenolic hydroxyl group damage during reactions.
Drug R&D：Serves as a chiral building block for peptide drug synthesis (e.g., anti-tumor, immunomodulators), improving target compound yield and purity.

Background Description

H-Tyr(tBu)-OEt, a tyrosine derivative, protects the phenolic hydroxyl group with a tert-butoxy group, commonly used in solid-phase peptide synthesis (SPPS) or solution synthesis. Its ethyl ester structure facilitates subsequent hydrolysis or coupling reactions, acting as a key intermediate in peptide drug research and peptide chain elongation.

Research Status

Current research focuses on optimizing protecting group introduction processes (e.g., enhancing chiral retention) and expanding applications in complex peptide synthesis. Some studies combine it with other protected amino acids to construct polypeptides with specific spatial structures, improving drug-target binding activity.

We can also customize related analogues and modified peptides including HPLC, MS, 1H-NMR, MS, HPLC, IR, UV, COA, MSDS.
