Description

(H-Hocys-Ome)2 2Hcl CAS NO 147857-42-9 is a high-purity, protected cysteine derivative used as a critical building block in advanced organic synthesis. This compound is essential for researchers and manufacturers requiring precise molecular control in complex chemical processes. It is primarily utilized in the development of novel pharmaceuticals, peptide-based therapeutics, and specialized biochemical research applications.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly those with sulfur-containing motifs.
• Peptide Chemistry: Used in solid-phase and solution-phase peptide synthesis (SPPS) for the controlled incorporation of protected cysteine residues.
• Bioconjugation: Acts as a precursor for creating linkers and functional handles in antibody-drug conjugates (ADCs) and other bioconjugation strategies.
• Chemical Biology Research: Employed in the study of protein structure, function, and interactions through site-specific modification.
• Protecting Group Strategy: The specific protecting groups (Hocys, Ome) make it valuable for multi-step syntheses requiring orthogonal deprotection.
• Material Science: Potential use in creating functionalized surfaces or polymers with thiol-reactive properties.
