1-ethenyl-3-methylbenzene

1-ethenyl-3-methylbenzene is an aromatic hydrocarbon compound with the molecular formula C9H10 and CAS number 100-80-1. This organic chemical features a benzene ring substituted with both a vinyl group (ethenyl) and a methyl group at specific positions. With a molecular weight of 118.18 g/mol, it belongs to the styrene family of compounds and serves as an important industrial chemical intermediate in various synthetic processes.

1-ethenyl-3-methylbenzene is a colorless to pale yellow liquid at room temperature with a characteristic aromatic odor. As an aromatic hydrocarbon with molecular formula C9H10, it exhibits typical properties of styrene derivatives including low water solubility but good solubility in organic solvents. The compound has a molecular weight of 118.18 g/mol and contains both aromatic and vinyl functional groups, making it reactive toward polymerization reactions.

1-ethenyl-3-methylbenzene is primarily used as a chemical intermediate in polymer synthesis and specialty chemical manufacturing. Its vinyl group makes it suitable for polymerization reactions to produce modified polystyrene resins and copolymers. The compound finds applications in the production of adhesives, coatings, and specialty plastics where specific performance characteristics are required. It may also serve as a building block in pharmaceutical and fine chemical synthesis.

1-ethenyl-3-methylbenzene should be handled using standard organic solvent precautions including wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume extraction to minimize vapor exposure. Avoid contact with skin and eyes, and prevent inhalation of vapors. Keep away from heat sources, sparks, and open flames due to its flammable nature.

1-ethenyl-3-methylbenzene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. As a vinyl compound, it may be prone to polymerization, so storage temperatures should be controlled and stabilizers may be present. Keep containers upright and properly labeled. Store away from strong oxidizing agents and incompatible materials. Regular inventory rotation helps ensure product quality and stability.

In case of skin contact with 1-ethenyl-3-methylbenzene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately. If ingested, do not induce vomiting and seek medical attention. Always consult safety data sheets for complete first aid procedures and contact emergency services if necessary.

1-ethenyl-3-methylbenzene must be disposed of according to local, national, and EU waste regulations as a hazardous organic waste. The material should not be discharged to sewers or the environment. Contact licensed waste disposal companies for proper treatment, which may include incineration at appropriate facilities. Empty containers should also be handled as hazardous waste. Always check current waste classification codes and follow applicable REACH and CLP disposal requirements.

1-ethenyl-3-methylbenzene is classified under ADR Class 3 (flammable liquids), Packing Group III for transportation purposes. This classification requires appropriate packaging, labeling, and documentation for road transport within Europe. Vehicles must comply with ADR regulations including proper placarding and driver certification. The relatively lower hazard level of Packing Group III allows for certain transport facilitations compared to higher hazard groups, but all ADR safety requirements must still be followed.

1-ethenyl-3-methylbenzene is subject to standard EU chemical regulations including REACH registration requirements and CLP classification and labeling regulations. The substance is not currently identified as a Substance of Very High Concern (SVHC) under REACH. Standard industrial chemical handling, storage, and workplace exposure regulations apply. Companies using this material must ensure compliance with relevant occupational health and safety directives and may need to conduct chemical safety assessments depending on usage volumes.
