Z-Trp(Boc)-OH.DCHA is primarily used in peptide synthesis as a protected form of tryptophan. The Boc (tert-butyloxycarbonyl) group safeguards the amino functionality, preventing unwanted reactions during peptide chain assembly. This compound is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase methods, where selective deprotection is required to achieve precise peptide sequences. Its stability under acidic conditions makes it suitable for stepwise elongation of peptides. Additionally, the DCHA (dicyclohexylamine) salt form enhances solubility in organic solvents, facilitating its use in various coupling reactions. This chemical is essential in the production of complex peptides for research, pharmaceuticals, and biotechnology applications.
