4-ethenylpyridine

4-ethenylpyridine is an organic compound with the molecular formula C7H7N and CAS number 100-43-6. It belongs to the pyridine family, featuring a vinyl group attached to the 4-position of the pyridine ring. With a molecular weight of 105.14 g/mol, this aromatic heterocyclic compound serves as an important building block in organic synthesis and polymer chemistry applications.

4-ethenylpyridine is typically a colorless to pale yellow liquid at room temperature with a characteristic pyridine-like odor. As an aromatic compound containing nitrogen, it exhibits basic properties and moderate polarity. The presence of both the pyridine ring and vinyl group influences its solubility characteristics, making it soluble in organic solvents while having limited water solubility.

4-ethenylpyridine is primarily used as a monomer in polymer synthesis and as an intermediate in pharmaceutical and agrochemical manufacturing. Its vinyl group enables polymerization reactions, making it valuable for creating specialized polymers with enhanced properties. Additionally, it serves as a building block in organic synthesis for developing complex molecules in research and industrial applications.

4-ethenylpyridine requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid contact with skin, eyes, and mucous membranes. Keep away from heat sources, sparks, and open flames due to its organic nature.

4-ethenylpyridine should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly closed to prevent contamination and evaporation. Store away from strong oxidizing agents, acids, and bases that could cause unwanted reactions. Maintain storage temperatures according to supplier specifications and ensure proper labeling of all containers.

In case of skin contact with 4-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 plenty of clean water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Seek medical attention if symptoms persist or worsen.

4-ethenylpyridine waste must be disposed of according to local, national, and international environmental regulations. Do not pour down drains or release into the environment. Contact licensed waste disposal companies for proper treatment and disposal. Ensure proper classification and documentation of waste streams. Small quantities may require special collection procedures through authorized chemical waste handlers.

4-ethenylpyridine is classified under ADR Class 6.1 (Toxic substances), Packing Group II, requiring specific packaging and labeling for transport. Use UN-approved packaging suitable for toxic liquids and ensure proper hazard labels are displayed. Transport vehicles must comply with ADR regulations including appropriate documentation, emergency equipment, and driver training for handling toxic substances.

4-ethenylpyridine is subject to REACH regulation in Europe, requiring registration for manufacturing or importing quantities above one tonne per year. It is not classified as a SVHC (Substance of Very High Concern) under current regulations. Users must comply with CLP regulation for classification and labeling, and follow local occupational safety guidelines for chemical handling.
