2-ethenylpyridine

2-ethenylpyridine is an organic chemical compound with the molecular formula C7H7N and CAS number 100-69-6. It belongs to the pyridine family, featuring a pyridine ring with an ethenyl (vinyl) group attached at the 2-position. With a molecular weight of 105.14 g/mol, this compound serves as an important intermediate in organic synthesis and polymer chemistry applications.

2-ethenylpyridine is a liquid at room temperature with a characteristic pyridine-like odor. As a vinyl-substituted pyridine derivative, it exhibits typical aromatic properties combined with alkene reactivity. The compound is soluble in organic solvents and has limited water solubility due to its aromatic nature. Its vinyl group makes it prone to polymerization under appropriate conditions.

2-ethenylpyridine is primarily used as a monomer in polymer synthesis and as an intermediate in organic chemistry. It serves in the production of specialty polymers, copolymers, and as a building block for pharmaceuticals and agrochemicals. The compound is also utilized in the synthesis of chelating agents and coordination compounds due to its nitrogen-containing heterocyclic structure.

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. Avoid contact with skin, eyes, and clothing. Use non-sparking tools and ensure proper grounding to prevent static electricity buildup during transfer operations.

2-ethenylpyridine should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep away from strong oxidizing agents and acids. Store in original containers with appropriate labeling. Maintain storage temperature below 25°C to prevent polymerization and degradation. Ensure compatibility with container materials.

In case of skin contact with 2-ethenylpyridine, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with plenty of water for 15 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 waste must be disposed of in accordance with local, national, and international regulations. Contact authorized waste disposal companies for proper treatment and disposal. Do not discharge into drains, waterways, or soil. Small quantities can be incinerated in approved facilities with appropriate emission controls. Ensure proper waste classification and documentation for disposal tracking.

2-ethenylpyridine is classified under ADR as Class 6.1 (Toxic substances), Packing Group II. Transport must comply with dangerous goods regulations including proper packaging, labeling, and documentation. Use UN-approved containers and ensure proper placarding of transport vehicles. Drivers must have appropriate dangerous goods training and carry emergency response information during transport.

2-ethenylpyridine is subject to REACH regulation in Europe and requires registration for manufacture or import above one tonne per year. It falls under CLP regulation for classification and labeling requirements. The substance is not identified as SVHC (Substance of Very High Concern). Compliance with occupational health and safety regulations is mandatory for workplace use.
