Safety Information
2-Vinylpyridine Usage And Synthesis
  • Chemical Propertiesdark brown liquid with an unpleasant odour
  • Chemical PropertiesThe odor of 2-vinylpyridine can be detected at exposure levels below 1 ppm (v/v). The unpleasant odor can be tolerated at concentrations that can produce acute symptoms and irritation. Special precautions should be taken to avoid skin and eye contact, as well as inhalation of the vapor.
  • Uses2-Vinylpyridine is a pyridine derivative used in the preparation of poly(2-vinylpyridine) via radical polymerization. 2-Vinylpyridine is used to improve effectiveness of protective polymer coatings on metals. It is a reagent for pyridylethylation for new protection method for active hydrogen compounds.. It is also used as basic materials for one of largest-selling plastic, manufacturing pharmaceuticals and bio-compounds.
  • Uses2-Vinylpyridine is a pyridine deriviative used in the preparation of poly(2-vinylpyridine) via radical polymerization. 2-Vinylpyridine is used to improve effectiveness of protective polymer coatings o n metals. 2-Vinylpyridine is an impurity of Betahistine (B324000).
  • General Description
    2-Vinylpyridine (2VP) is a water soluble pyridine derivative that can be used in the synthesis of poly(2-vinylpyridine) (P2VP) by anionic polymerization. It can be industrially prepared by treatment of 2-methylpyridine with an aqueous solution of formaldehyde in a temperature range of 150-200°C.
  • CarcinogenicityNo definitive information on carcinogenicity of the vinylpyridines was found. However, when either 2-vinylpyridine or 4-vinylpyridine was injected intraperitoneally into A/J mice (200 mmol/animal), there was no significant increase in lung adenoma or any other tumors. None was listed as a carcinogen by IARC, OSHA, NTP, and ACGIH.
  • Purification MethodsSteam distil it, then dry it with MgSO4 and distil it in a vacuum. [Beilstein 20 H 256, 20 III/IV 2884, 20/6 V 211.]
