Description

Boc-Asp-Ochex Dcha CAS NO 200283-00-7 is a protected aspartic acid derivative, specifically the tert-butoxycarbonyl (Boc) protected form with a cyclohexyl ester (Ochex) and a dicyclohexylamine (Dcha) salt. This compound is a critical building block in the synthesis of complex peptides and pharmaceutical intermediates, offering enhanced solubility and handling properties. It is primarily utilized by research institutions and manufacturers in the pharmaceutical and biotechnology sectors for drug discovery and development processes.

Application

• Peptide Synthesis: Serves as a key protected amino acid derivative in solid-phase and solution-phase peptide synthesis (SPPS).
• Pharmaceutical Intermediates: Used in the research and production of active pharmaceutical ingredients (APIs) and therapeutic peptides.
• Bioconjugation: Acts as a precursor for creating peptide-based conjugates for targeted drug delivery systems.
• Biochemical Research: Employed in academic and industrial laboratories for studying protein structure, function, and enzyme-substrate interactions.
• Protecting Group Strategy: Utilized in multi-step organic syntheses where selective protection and deprotection of the aspartic acid side chain is required.
