L-Aspartic acid, N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, 1,4-bis(1,1-dimethylethyl) ester

Description:
L-Aspartic acid, N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, 1,4-bis(1,1-dimethylethyl) ester, with CAS number 129460-17-9, is a derivative of the amino acid L-aspartic acid, modified to include a protective fluorenylmethoxycarbonyl (Fmoc) group and tert-butyl ester groups. This compound is typically used in peptide synthesis as a building block due to its ability to protect the amino group during reactions. The Fmoc group allows for selective deprotection under mild basic conditions, facilitating the stepwise assembly of peptides. The tert-butyl ester groups enhance the compound's solubility and stability, making it suitable for various organic synthesis applications. In terms of physical properties, it is likely to be a solid at room temperature, with a relatively high melting point, and it may exhibit moderate solubility in organic solvents. The presence of multiple functional groups contributes to its reactivity, making it a valuable intermediate in the synthesis of more complex molecules in medicinal chemistry and biochemistry.
