2-ethenylpyridine is a liquid at room temperature with characteristic aromatic properties typical of pyridine derivatives. The compound contains both a pyridine ring and a vinyl functional group, making it reactive for polymerization reactions. Its molecular structure allows for various chemical transformations and interactions due to the nitrogen heteroatom and the unsaturated vinyl moiety.

2-ethenylpyridine is primarily used as a monomer in polymer synthesis and as an intermediate in organic chemical manufacturing. It serves in the production of specialty polymers, resins, and copolymers with unique properties. The compound is also utilized in pharmaceutical synthesis, agrochemical production, and as a building block for various nitrogen-containing organic compounds in research and industrial applications.

2-ethenylpyridine should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation exposure. Given its ADR classification as Class 6.1 Group II, the substance requires careful handling as a toxic material. Avoid contact with skin, eyes, and prevent ingestion during use.

2-ethenylpyridine should be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed to prevent contamination and evaporation. Due to the vinyl group, store away from polymerization initiators and strong oxidizing agents. Maintain storage temperatures as recommended by the supplier and ensure proper labeling according to transport regulations.

In case of skin contact with 2-ethenylpyridine, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention.

2-ethenylpyridine must be disposed of according to local and national hazardous waste regulations. The compound should not be discharged into drains, sewers, or the environment. Contact licensed waste disposal companies for proper treatment and disposal. Waste containers must be properly labeled and handled according to ADR Class 6.1 requirements during transport to disposal facilities.

2-ethenylpyridine is classified under ADR Class 6.1, Packing Group II, indicating it is a toxic substance requiring special transport precautions. Packages must comply with UN packaging requirements for toxic materials. Transport vehicles must carry appropriate hazard placards and emergency response information. Only authorized personnel should handle the substance during loading, transport, and unloading operations.

2-ethenylpyridine is subject to European chemical regulations including REACH registration requirements and CLP classification standards. The substance is not identified as a SVHC (Substance of Very High Concern) under current REACH regulations. Companies using this chemical must comply with safety data sheet requirements, proper labeling, and workplace exposure limits as established by relevant European authorities.
