Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
4-Vinylpyridine (4VP) does not hydrolyse in water to a significant degree. Absorption of water promotes autopolymerisation (see stability studies). The behaviour of 4-vinylpyridine in the atmosphere was assumed to be similar to that of structural analogue 2-vinylpyridine, which does react in the atmosphere with ozone, hydroxyl and nitrate radicals, to form primarily 2-pyridinecarboxyaldehyde. Under ambient atmospheric conditions, the lifetime of 2VP due to reaction with hydroxyl radicals, nitrate radicals and ozone is approximately 3 hours, 4 hours and 1 day, respectively. This is similar to the well-known atmospheric fate pathway of styrene conversion to benzaldehyde.
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.
