Overview
Trimethyltin (TMT) is an organotin compound with significant industrial and research applications. It is primarily used as a stabilizer in the production of polyvinyl chloride (PVC) and as a catalyst in organic synthesis. Due to its high toxicity, TMT is subject to strict handling and storage regulations. Organotin compounds like TMT have been studied extensively for their neurotoxic effects, making them important in neurological research. However, their industrial use has declined in some regions due to environmental and health concerns.
Physical and Chemical Properties
Trimethyltin is a colorless to pale yellow liquid with a molecular weight of 178.84 g/mol. It has a density of 1.17 g/cm³ and a boiling point of 77-78 °C at standard pressure. TMT is highly soluble in organic solvents but insoluble in water. The compound is highly reactive, particularly with oxidizing agents and water, which can lead to violent reactions. Its flammability and toxicity necessitate careful handling, including the use of personal protective equipment (PPE) and proper ventilation.
Main Applications
Trimethyltin is widely used as a stabilizer in PVC production, where it prevents degradation during processing and extends the material's lifespan. It also serves as a catalyst in organic synthesis, particularly in reactions involving carbon-carbon bond formation. In research, TMT is employed as a neurotoxic agent to study neurodegenerative diseases. Its ability to induce selective neuronal damage makes it a valuable tool in neuroscience, though its use is tightly regulated due to safety concerns.
Safety and Storage
Due to its high toxicity and reactivity, Trimethyltin must be stored in a cool, dry, and well-ventilated area, away from oxidizing agents and moisture. Containers should be tightly sealed and labeled with appropriate hazard warnings. Handling TMT requires strict adherence to safety protocols, including the use of gloves, goggles, and respiratory protection. Spills should be managed with extreme caution, and disposal must comply with local environmental regulations to prevent contamination.
B2B Procurement Guide
When purchasing Trimethyltin, businesses should prioritize suppliers with verified certifications and a track record of compliance with safety and environmental standards. Pricing varies based on purity and quantity, with reference prices typically ranging from $50 to $100 per gram. Buyers should also ensure that transportation and storage conditions meet regulatory requirements. Documentation, including safety data sheets (SDS) and certificates of analysis, should be reviewed to confirm product specifications and handling instructions.
