Fmoc-Asp(OtBu)-OH is a protected amino acid derivative widely used in solid-phase peptide synthesis. Its core process involves Fmoc protection on the alpha-amino group and tert-butyl ester protection on the side-chain carboxyl group to prevent racemization. The molecular formula is C19H27NO6 with CAS number 15603-48-6.
Store under inert atmosphere at -20°C to maintain stability. Avoid direct skin contact due to potential sensitization. Do not use in clinical settings without rigorous purification protocols to remove residual solvents.
