CAS 19955-99-8: 3-VINYLBENZALDEHYDE
Description:3-Vinylbenzaldehyde, with the CAS number 19955-99-8, is an organic compound characterized by its vinyl group and aldehyde functional group attached to a benzene ring. It is a colorless to pale yellow liquid with a distinct aromatic odor. The compound is known for its reactivity, particularly in polymerization reactions, due to the presence of the vinyl group, which can participate in various chemical reactions, including addition and cross-linking. 3-Vinylbenzaldehyde is soluble in organic solvents and has limited solubility in water. It is primarily used in the synthesis of polymers, resins, and other organic compounds. Additionally, it may serve as an intermediate in the production of fragrances and flavoring agents. Safety considerations include handling it with care, as it may be irritating to the skin, eyes, and respiratory system. Proper storage in a cool, dry place away from light is recommended to maintain its stability and prevent polymerization.
