Description

Tetrathiomolybdate is an inorganic compound containing molybdenum coordinated by four sulfur atoms, known for its role as a potent and selective copper chelator. This property makes it a critical research chemical and a potential therapeutic agent for conditions involving copper dysregulation. It is primarily utilized in biochemical research, pharmaceutical development, and as a catalyst precursor in specialized chemical synthesis. The compound is commercially available to meet the stringent requirements of industrial and academic laboratories worldwide.

Application

• Biochemical Research: Used as a specific inhibitor of copper-dependent enzymes (e.g., cytochrome c oxidase, superoxide dismutase) to study copper metabolism and related pathways.
• Pharmaceutical Development: Investigated as a potential therapeutic agent for Wilson's disease, cancer angiogenesis, and other disorders linked to copper overload.
• Catalyst Precursor: Serves as a starting material for the synthesis of molybdenum sulfide-based catalysts used in hydrodesulfurization (HDS) and other petrochemical processes.
• Analytical Chemistry: Employed as a reagent for the spectrophotometric determination of copper and other metals in complex matrices.
• Material Science: Used in the preparation of thin films and nanomaterials, particularly molybdenum disulfide (MoS₂), for electronic and lubricant applications.
• Veterinary Medicine: Studied for the treatment of copper toxicosis in sheep and other animals.

Quality Control

Our Tetrathiomolybdate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (by titration or ICP), heavy metal limits, and moisture content. Our quality systems are designed to support research and development requiring high-purity, reliable chemical reagents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and may require desiccant. Keep away from incompatible materials such as strong oxidizing agents.
