Description

Cystamine Sulfate CAS NO 16214-16-7 is a high-purity, crystalline organic compound widely utilized as a critical intermediate and reagent in advanced chemical synthesis. Its primary value lies in its role as a versatile disulfide-containing building block, essential for creating cross-linked structures and modifying biomolecules. This product is particularly vital for researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors, where precise molecular control is paramount.

Application

• Pharmaceutical Intermediate: Key starting material or intermediate in the synthesis of novel drug candidates, particularly those targeting neurological or metabolic pathways.
• Bioconjugation & Protein Modification: Used as a homobifunctional crosslinker to introduce disulfide bonds or thiol-reactive groups into proteins, antibodies, and peptides for research and therapeutic applications.
• Polymer Chemistry: Serves as a monomer or chain extender in the production of specialty polymers with disulfide linkages, which can impart redox-responsive or degradable properties.
• Biochemical Research: Essential reagent for studying oxidative stress, thiol-disulfide exchange mechanisms, and as a precursor for generating cysteamine in experimental models.
• Surface Functionalization: Employed to modify material surfaces (e.g., gold nanoparticles, biosensors) with thiol-reactive groups for enhanced biocompatibility or specific binding.
