Description

Selenocystamine Dihydrochloride is a high-purity, organoselenium compound of significant interest in biochemical and pharmaceutical research. Its core value lies in its role as a versatile precursor and building block for synthesizing selenium-containing biomolecules and functional materials. This compound is essential for researchers and manufacturers in the fields of bioconjugation, peptide synthesis, and materials science, where the introduction of selenium atoms is required for specific catalytic, structural, or labeling functions.

Application

• Bioconjugation and Cross-linking Agent: Used to introduce selenium-based functional groups or create diselenide bonds for protein and antibody modification.
• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel selenium-containing drug candidates and active pharmaceutical ingredients (APIs).
• Peptide Synthesis: Employed as a protected selenium analog of cystamine for the solid-phase or solution-phase synthesis of selenopeptides.
• Materials Science: Acts as a monomer or linker for creating selenium-functionalized polymers, hydrogels, and nanomaterials with redox-responsive properties.
• Research Reagent: Utilized in biochemical studies to investigate the role of selenium in enzyme mimics, antioxidant systems, and redox biology.
• Catalyst Development: A starting material for synthesizing organoselenium catalysts used in green chemistry and organic synthesis.
