Methyl 2-methylprop-2-enoate

Methyl 2-methylprop-2-enoate is an organic chemical compound with the molecular formula C5H8O2 and CAS number 80-62-6. Also known as methyl methacrylate (MMA), it is a volatile ester with a molecular weight of 100.12 g/mol. This substance is classified as a flammable liquid and is considered hazardous due to its potential for skin irritation, sensitization, and specific target organ toxicity. It carries the danger signal word and requires careful handling in industrial applications.

Methyl 2-methylprop-2-enoate is a colorless, volatile liquid at room temperature with a characteristic acrid odor. It has a molecular weight of 100.12 g/mol and the chemical formula C5H8O2. The substance is moderately soluble in water but highly soluble in organic solvents. It exhibits high volatility and flammability, classified as Flammable Liquid Category 2. The compound readily polymerizes under certain conditions and requires stabilizers to prevent unwanted reactions during storage and transport.

Methyl 2-methylprop-2-enoate serves as a crucial monomer in the production of polymethyl methacrylate (PMMA) plastics, commonly known as acrylic glass or plexiglass. It is extensively used in manufacturing transparent plastics, coatings, adhesives, and sealants. The chemical industry utilizes it for producing dental materials, bone cement, paints, and various polymer composites. Its polymerization properties make it valuable in creating durable, weather-resistant materials for automotive, construction, and optical applications.

Methyl 2-methylprop-2-enoate requires careful handling due to its flammable and irritating properties. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and respiratory protection in poorly ventilated areas. Work should be conducted in well-ventilated spaces away from ignition sources, as it carries Flammable Liquid Category 2 classification. Avoid direct skin contact due to its skin irritation and sensitization potential (Skin Irrit. 2; Skin Sens. 1). Ensure proper grounding and bonding when transferring the substance.

Methyl 2-methylprop-2-enoate must be stored in a cool, well-ventilated area away from heat sources, sparks, and open flames due to its Flammable Liquid Category 2 classification. Storage containers should be tightly sealed and made of compatible materials. The substance should be kept away from strong oxidizers and polymerization initiators. Temperature control is crucial to prevent unwanted polymerization. Storage areas must comply with fire safety regulations and include appropriate fire suppression systems designed for flammable liquids.

Immediate action is required upon contact with methyl 2-methylprop-2-enoate due to its irritating and sensitizing properties. For skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. Seek medical attention if irritation persists or if large amounts were involved. Never induce vomiting if swallowed.

Methyl 2-methylprop-2-enoate must be disposed of as hazardous waste in accordance with local and European waste regulations. The substance cannot be discharged into sewers, waterways, or regular waste streams due to its flammable and potentially harmful properties. Disposal should be conducted through licensed hazardous waste treatment facilities capable of handling flammable organic compounds. Empty containers may retain hazardous residues and require proper cleaning or disposal as contaminated packaging. Always consult local environmental authorities for specific disposal requirements.

Methyl 2-methylprop-2-enoate is classified under ADR Class 3 (flammable liquids), Packing Group II, indicating moderate danger during transport. Transportation requires appropriate UN-approved packaging designed for flammable liquids and proper hazard labeling including GHS02 and GHS07 pictograms. Vehicles must carry appropriate fire extinguishing equipment and emergency response information. Drivers require ADR certification for dangerous goods transport. The substance must be secured to prevent movement and protected from heat sources during transit. Proper documentation and emergency contact information are mandatory.

Methyl 2-methylprop-2-enoate is regulated under European REACH and CLP regulations, requiring registration for commercial use and proper classification labeling. It carries multiple hazard classifications including Flammable Liquid 2, STOT SE 3, Skin Irritant 2, and Skin Sensitizer 1, mandating specific safety measures. The substance is not currently listed as a Substance of Very High Concern (SVHC). Occupational exposure limits may apply in workplace environments. Users must maintain safety data sheets and ensure compliance with national chemical safety regulations across EU member states.
