Concentration: 98-100%
CAS Number: 97-90-5
Impurities: Minor amounts of monoester, stabilizer (usually MEHQ, less than 200 ppm)
Inhalation: Move to fresh air, monitor for symptoms like dizziness or coughing
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water
Eye Contact: Rinse immediately with plenty of water for 15 minutes, seek medical advice immediately
Ingestion: Do not induce vomiting; rinse mouth, seek medical help
Most Important Symptoms: Skin redness, irritation, possible allergic reaction, respiratory irritation
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray
Unsuitable Media: Direct water stream can spread flames
Special Protective Equipment: Wear self-contained breathing apparatus, full firefighting gear
Specific Hazards: Vapors may form explosive mixtures with air, thermal decomposition releases toxic gases including carbon monoxide, carbon dioxide, and irritating fumes
Advice for Firefighters: Cool containers with flooding quantities of water until well after fire is out, control run-off to prevent environmental contamination
Personal Precautions: Evacuate unprotected personnel, ventilate area, wear protective equipment
Environmental Precautions: Prevent entry into sewers or waterways
Clean-up Methods: Absorb with inert material like vermiculite or sand, scoop into appropriate containers for disposal, wash spill area with detergent solution
Preventative Actions: Eliminate all ignition sources, control vapor accumulation
Handling: Use only in well-ventilated areas; avoid skin and eye contact, avoid breathing vapors; ground and bond containers when transferring; keep away from heat, sparks, and open flames
Storage: Keep container tightly closed, store in cool, dry place away from direct sunlight, ignition sources, and incompatible materials such as strong oxidizers; keep in original packaging or approved container
Engineering Controls: Use local exhaust ventilation to maintain vapor concentrations below exposure limits
Personal Protective Equipment: Chemical-resistant gloves (nitrile, butyl rubber), safety goggles or face shield, lab coat, flame-resistant clothing, approved respiratory protection if exposure limits are approached
Occupational Exposure Limits: No ACGIH TLV or OSHA PEL established as of latest publications; minimize exposure as precaution
Hygiene Measures: Wash hands before eating, drinking, or smoking, avoid contact with skin and eyes, remove contaminated clothing promptly
Appearance: Colorless, clear liquid
Odor: Slight sweet, pungent odor
pH: Not applicable
Boiling Point: 213°C (415°F)
Melting Point: -40°C (-40°F)
Flash Point: 110°C (230°F) (Closed cup)
Explosive Limits: Data not well established
Vapor Pressure: 0.03 mm Hg (20°C)
Density: 1.08 g/cm³ (20°C)
Solubility: Slightly soluble in water, miscible with common organic solvents
Chemical Stability: Stable under recommended storage conditions with suitable antioxidants
Conditions to Avoid: Heat, open flames, sunlight, sources of ignition, prolonged storage without inhibitor
Incompatible Materials: Strong oxidizers, acids, and bases, free radical initiators
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, methyl methacrylate, acrid fumes
Polymerization: May undergo hazardous polymerization if heated, contaminated, or devoid of stabilizer
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Toxicity: Oral LD50 (rat): approximately 10,000 mg/kg; low toxicity, not expected to be acutely harmful at normal exposure levels
Skin Corrosion/Irritation: Causes irritation, may cause allergic reaction, drying, redness
Eye Damage/Irritation: Causes irritation, potential risk of damage
Respiratory Effects: Vapor may cause irritation to respiratory tract
Sensitization: Possible skin sensitizer
Chronic Effects: Repeated or prolonged exposure may lead to skin sensitization, dermatitis
Ecotoxicity: Harmful to aquatic life, limited biodegradation over short term
Persistence and Degradability: Slowly biodegradable
Bioaccumulative Potential: Expected to have low potential for bioaccumulation
Mobility in Soil: Likely to leach if accidentally released in large quantities
Other Adverse Effects: Vapor releases may contribute to ground-level ozone formation, though impact is minor compared to industrial scale VOCs
Disposal Methods: Dispose of contents and container according to local, regional, and national regulations; incineration or chemical treatment in approved facilities
Precautions for Disposal: Do not discharge into drains or the environment; unused product may require special handling as hazardous waste
Container Disposal: Triple rinse and offer for recycling or disposal at approved site
