Chemical Name: 1,4-Butanediol Dimethacrylate
CAS No.: 2082-81-7
Percent: ≥ 99% by weight
Impurities: Trace inhibitors (for example: hydroquinone monomethyl ether, <0.1%) to prevent premature polymerization
Inhalation: Remove to fresh air, monitor for respiratory symptoms; seek medical advice if discomfort persists
Skin Contact: Remove contaminated clothing and wash affected area with soap and water for several minutes; seek attention if irritation develops
Eye Contact: Rinse eyes cautiously with water for several minutes (hold eyelids apart); remove contact lenses if easy; continue rinsing and seek medical attention
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical advice
Advice to Doctors: Treat symptomatically, pay attention to mucosal irritation
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, foam, or water spray (avoid high-pressure water jets)
Specific Hazards: Produces toxic fumes (carbon monoxide, carbon dioxide, acrid smoke) during combustion
Protective Equipment: Wear full protective gear and self-contained breathing apparatus
Firefighting Precautions: Stay upwind to avoid fumes, keep containers cool with water spray, avoid runoff into waterways
Explosion Hazards: Vapors may form explosive mixtures with air above flash point
Personal Precautions: Avoid skin and eye contact, ventilate area; wear protective equipment (gloves, goggles, dust mask/respirator)
Environmental Precautions: Prevent spillage from entering drains, soil, or waterways; contain spill with inert absorbent material (sand, earth)
Clean Up Methods: Scoop up spilled material, place in labeled container for disposal, wash spill area thoroughly with water and detergent
Handling Precautions: Use with adequate ventilation, avoid inhalation of vapors or contact with skin/eyes, use proper PPE (gloves, safety glasses/goggles, protective clothing)
Hygiene Measures: Wash hands after handling, take off and wash contaminated clothing before reuse
Storage Conditions: Store in tightly closed containers away from heat, sparks, flames, oxidizing agents, and water; keep refrigerated or at room temperature, protected from direct sunlight
Special Sensitivity: Contains stabilizers to reduce risk of unwanted polymerization — never add accelerants or catalysts during storage
Engineering Controls: Use only in well-ventilated areas, local exhaust recommended at points of vapor/dust generation
Exposure Limits: No established regulatory exposure limit; workplace air monitoring can help reduce inhalation risk
Personal Protective Equipment (PPE): Impermeable gloves (nitrile or neoprene), safety goggles/face shield, protective clothing, in cases of insufficient ventilation use organic vapor respirator
Hygiene: Do not eat, drink, or smoke during handling, wash thoroughly before breaks and after work

Acute Toxicity: Oral LD50 (rat): >5000 mg/kg; Dermal LD50 (rabbit): >2000 mg/kg
Inhalation: May cause respiratory tract irritation (excessive exposure over time poses risk)
Skin Irritation: Causes moderate irritation, possible allergic reaction after repeated contact
Eye Irritation: Causes moderate to severe eye irritation
Chronic Effects: Repeated or prolonged skin exposure can sensitize skin
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, OSHA
Mutagenicity/Reproductive Toxicity: Genotoxicity data limited, no strong evidence for reproductive toxicity from available studies
Other Effects: May worsen symptoms of pre-existing skin disorders
Ecotoxicity: Moderately toxic to aquatic organisms, may cause long-term adverse effects in aquatic environment
