Product Name:Z-ASP-OBZL
English Name:Z-ASP-OBZL
CAS No.:4779-31-1
Aliases:Z-L-aspartic acid 1-benzyl ester, N-Carbobenzoxy-L-aspartic acid α-benzyl ester, CBZ-L-aspartic acid 1-benzyl ester
Molecular Formula:C19H19NO6
Physical Properties:White to off-white crystalline powder, freely soluble in dichloromethane, N,N-dimethylformamide and other organic solvents, insoluble in water. Melting point approximately 105-110°C, density about 1.3 g/cm³. Optically active; store sealed, protected from light, at low temperature and dry conditions.
Uses:Used as a key intermediate in peptide synthesis, where the α-amino group is protected by benzyloxycarbonyl and the α-carboxyl group forms a benzyl ester, allowing the β-carboxyl group to selectively participate in coupling reactions. Widely applied in the synthesis of pharmaceutical peptides, dendrimers, and fine chemicals.
Technical Specifications:
Assay (HPLC) ≥98.5%
Appearance: white to off-white crystalline powder
Molecular formula C19H19NO6, molecular weight 357.36
Melting point range: 105-110°C
Loss on drying ≤0.5%
