Product Name: Tributyltin Methacrylate
Chemical Formula: C19H36O2Sn
CAS Number: 2155-70-6
Physical Appearance: Colorless to pale yellow liquid, characteristic odor
Major Use: Commonly found in marine paints, pesticides, and certain coatings due to its antifouling capabilities
Harmful if inhaled or ingested
Skin Irritation: Causes serious irritation upon contact
Eye Damage: Leads to severe irritation or damage
Acute Toxicity: Central nervous system depression and organ toxicity possible at high exposures
Environmental Hazard: Highly toxic to aquatic organisms with long-term impact on marine ecosystems
Main Component: Tributyltin Methacrylate
Other Impurities: Contains small amount of methacrylic acid and related organotin compounds
Concentration: Pure or formulated as ingredient in coatings or treatments, exact percentages depend on manufacturing source
Inhalation: Move to fresh air and seek medical attention if breathing becomes difficult
Skin Contact: Remove contaminated clothing and wash affected area thoroughly with soap and water
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, and seek medical help
Ingestion: Rinse mouth, do not induce vomiting, and call for medical assistance immediately
Suitable Extinguishing Media: Foam, dry chemical, or carbon dioxide
Specific Hazards: Releases toxic gases such as carbon monoxide, carbon dioxide, and tin oxides when burned
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective gear due to chemical vapor risks
Explosion Risk: As a liquid with low flash point, poses moderate fire risk in enclosed areas
Personal Precautions: Use chemical-resistant gloves, protective eyewear, and respirators
Environmental Precautions: Prevent product from entering waterways, sewers, or draining into soil
Containment: Dike and absorb spills with inert material such as sand or earth
Cleanup: Collect residues for hazardous waste disposal using sealed containers, decontaminate area with suitable cleaning agents
Handling: Use only in well-ventilated spaces, avoid breathing vapors, prevent all skin and eye contact
Storage: Store in tightly closed containers away from heat sources, sunlight, acids, and oxidizers, keep area cool and dry
Special Requirements: Regular inspections for leaks or container degradation, keep out of reach of children and unauthorized personnel
Engineering Controls: Fume hoods, local exhaust ventilation, and proper process enclosures
Personal Protection: Chemical splash goggles, impervious gloves, long-sleeve clothing, and suitable mask or respirator
Hygiene Measures: Regular hand washing, do not eat or drink near work area, dispose of contaminated PPE properly
Physical State: Liquid at room temperature
Color: Colorless to light yellow
Odor: Characteristic, slightly pungent
Flash Point: Below 100°C, fire risk in confined environments
Solubility: Limited in water, good in most organic solvents
Vapor Pressure: Moderate, may cause build-up of hazardous vapors especially in closed systems
Density: Approximately 1.15–1.20 g/cm³
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Reacts with strong oxidizers, acids, bases and some metals
Hazardous Decomposition: Carbon monoxide, carbon dioxide, tin compounds, and possibly methacrylic vapors during combustion
Avoid: High temperatures and incompatible storage conditions increase risk of decomposition and environmental hazard
Inhalation: May cause respiratory tract irritation, headache, dizziness, and neurological symptoms at high dose
Skin and Eye Contact: Irritant, sensitizer in susceptible individuals
Chronic Exposure: May pose risk of liver, kidney, and reproductive toxicity, especially through occupational exposure over time
Acute Toxicity: Can be fatal if swallowed or absorbed in significant quantities, LD50 data for oral exposure in rats reported between 25–100 mg/kg
Carcinogenicity: No clear evidence, but classified as potential risk by several regulatory bodies for tin compounds
Persistence: Highly persistent in aquatic environments, not readily biodegradable
Bioaccumulation: Tends to accumulate in marine organisms and food chains
Aquatic Toxicity: Severe toxicity to both freshwater and marine life, particularly mollusks, crustaceans, and some fish
Long-Term Effects: Impacts reproductive development in marine organisms, degrades at a slow rate causing environmental build-up over years
Hazardous Waste: Requires special disposal via permitted chemical waste treatment facility
Avoid: Do not discharge into drains, soil, or natural water systems
Recommended Practice: Collect in sealed, labeled containers and engage certified hazardous waste professionals for disposal
Classification: Regulated as a hazardous material for road, rail, sea, and air
Packaging: Use corrosion-resistant, sealed containers clearly marked for hazardous contents
Spill Controls: Emergency kits should be available in transit; all handlers trained in chemical spill response
Restrictions: Many jurisdictions limit shipment due to the toxicity profile and persistent environmental hazards
Use Restrictions: Heavily regulated or banned in marine paints in numerous countries due to environmental impact
Workplace Safety Standards: Covered by occupational exposure limits for organotin compounds in many regions
Environmental Directives: Subject to global treaties such as the International Maritime Organization’s antifouling conventions banning uses in ship hull coatings
Reporting Requirements: Accidental releases, spills, or occupational exposures must often be reported to local authorities, especially near water systems
