Description

Cystamine Dihydrochloride is a high-purity organic compound widely utilized as a critical intermediate and cross-linking agent. Its primary value lies in its ability to form disulfide bonds, making it essential for biochemical research, pharmaceutical synthesis, and material science. This product is particularly important for researchers and manufacturers in the pharmaceutical, biotechnology, and polymer industries who require a reliable source of a stable, reactive diamine derivative.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of various active pharmaceutical ingredients (APIs), including potential treatments for neurodegenerative and metabolic disorders.
• Bioconjugation & Cross-linking: Used to introduce disulfide linkages or thiol-reactive groups into proteins, peptides, and other biomolecules for research, diagnostics, and drug delivery systems.
• Polymer Chemistry: Serves as a monomer or cross-linker in the production of specialty polymers, hydrogels, and resins with tailored mechanical and responsive properties.
• Radiation Protectant Research: Investigated in biochemical studies for its potential radioprotective effects due to its ability to scavenge free radicals.
• Surface Modification: Employed to functionalize surfaces (e.g., gold, silica) with amine or thiol groups for sensor development and chromatography media.
• Biochemical Reagent: Used in laboratories as a reducing agent for disulfide bonds in proteins and as a precursor for synthesizing cysteamine and related compounds.

Quality Control

Our Cystamine Dihydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-grade specifications suitable for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed and desiccated to maintain stability and prevent degradation.
