CAS 922-64-5

2-Methylenepropanedinitrile

Description:

2-Methylenepropanedinitrile, also known by its CAS number 922-64-5, is an organic compound characterized by the presence of two cyano (nitrile) groups attached to a methylene bridge. This compound is a colorless to pale yellow liquid at room temperature and is known for its strong, pungent odor. It is soluble in polar organic solvents but has limited solubility in water. The presence of the nitrile functional groups imparts significant reactivity, making it useful in various chemical syntheses, particularly in the production of polymers and other organic compounds. 2-Methylenepropanedinitrile can undergo polymerization, leading to the formation of polyacrylonitrile-like materials. It is important to handle this compound with care, as it can be toxic and may pose health risks upon exposure. Proper safety measures, including the use of personal protective equipment and adequate ventilation, are essential when working with this substance in a laboratory or industrial setting.
