For professionals working with chemical intermediates, a thorough understanding of their properties and safe handling procedures is paramount. 4-Vinylpyridine (CAS 100-43-6) is a notable compound used across various industries, from pharmaceuticals to polymer manufacturing. Knowing its characteristics ensures efficient and safe utilization.

4-Vinylpyridine, with the molecular formula C7H7N, is a pyridine derivative featuring a vinyl group. Its typical appearance is a dark brown to yellow liquid. Key physical properties include a molecular weight of 105.14, a boiling point of 173.6 °C at 760 mmHg, and a flash point of 51.7 °C, indicating it is a flammable liquid. The product is often stabilized with inhibitors like hydroquinone or tert-butylcatechol (TBC) to prevent premature polymerization during storage and transport. Water solubility is moderate, at 29 g/L at 20 °C.

Its primary applications include acting as a monomer for producing poly(4-vinylpyridine) and serving as an intermediate in organic synthesis, particularly for pharmaceutical compounds. Its reactive vinyl group allows it to participate in addition polymerization and other chemical reactions crucial for creating complex molecules.

Safe handling of 4-Vinylpyridine requires adherence to standard chemical safety protocols. Given its flammable nature and potential health hazards (often associated with toxicity and irritation), it should be handled in a well-ventilated area, preferably under a fume hood. Personal protective equipment (PPE) such as chemical-resistant gloves, safety goggles, and protective clothing is essential. In case of contact, immediate rinsing with plenty of water is advised.

For storage, it’s recommended to keep 4-Vinylpyridine in a cool, dry, and well-ventilated place, away from heat sources, sparks, and open flames. It should also be stored separately from incompatible materials, such as strong oxidizing agents and acids. Utilizing the correct packaging, like 25kg or 200kg drums provided by a reliable 4-Vinylpyridine manufacturer, ensures product integrity and safety.

By respecting its chemical properties and implementing appropriate handling and storage measures, businesses can effectively and safely integrate 4-Vinylpyridine CAS 100-43-6 into their industrial processes.
