Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
2-Vinylpyridine is a clear to light yellow liquid with an unpleasant odor. It is flammable, with a flashpoint of 50 oC. It has a vapour pressure of 25.3 hPa. It is very soluble in water, and partitions preferentially into water (log Kow = 1.54). 2VP is a reactive monomer and is supplied with the addition of a polymerisation inhibitor (tert-butylcatechol). Absorption of water, introduction of impurities or warming can result in consumption of the inhibitor, with resultant autopolymerisation. If this exothermic process occurs, there could potentially be a run-away reaction with increased pressure, rupture of containers, and fire. Technical guidance instructions on storage and handling, in combination with safety data sheet instructions, have contributed to its history of safe use.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
