4-Vinylpyridine Usage And Synthesis

Chemical Properties

dark brown to yellow liquid

Contact allergens

4-Vinyl pyridine was used as a monomer in polymer chemistry and induced nonimmunological contact urticaria and allergic contact dermatitis. No crossreactivity is observed between pyridine derivatives.

Purification Methods

6 2 . Purify the monomer by fractional distillation under a good vacuum and in a N2 atmosphere and store it in sealed ampoules under N2, and keep it in the dark at -20o. The picrate has m 175-176o.
