Description : Ketotifen is a second-generation noncompetitive H1-antihistamine and mast cell stabilizer. It is most commonly sold as a salt with fumaric acid, ketotifen fumarate, and is available in two forms. In its ophthalmic form, it is used to treat allergic conjunctivitis,or the itchy red eyes caused by allergies. In its oral form, it is used to preventasthma attacks. - Molecular Weight :425.5
- Boiling Point :250-263 °C(lit.)
- Melting Point :> 191°C (dec.)
- Purity :> 98%
