Fmoc-D-Asp-OTBU

Description:

Fmoc-D-Asp-OTBU, or Fmoc-D-aspartic acid tert-butyl ester, is a protected form of the amino acid aspartic acid, commonly used in peptide synthesis. The Fmoc (9-fluorenylmethoxycarbonyl) group serves as a protective group for the amino functionality, allowing for selective reactions during peptide assembly. The tert-butyl ester (OTBU) protects the carboxylic acid group, enhancing the stability and solubility of the compound in organic solvents. This compound is typically white to off-white in appearance and is soluble in common organic solvents like dichloromethane and dimethylformamide. It is stable under standard laboratory conditions but should be stored in a cool, dry place to prevent degradation. Fmoc-D-Asp-OTBU is widely utilized in solid-phase peptide synthesis due to its compatibility with various coupling reagents and its ability to facilitate the formation of peptide bonds. Its use allows for the efficient synthesis of peptides with specific sequences, which are crucial in research and therapeutic applications.
