CAS 126-98-7: Methacrylonitrile

Description: Methacrylonitrile, with the CAS number 126-98-7, is an organic compound characterized by its colorless to pale yellow liquid form and a distinctive acrid odor. It is a nitrile derivative of methacrylic acid, featuring a vinyl group that contributes to its reactivity, particularly in polymerization processes. Methacrylonitrile is soluble in organic solvents such as acetone and ethanol but has limited solubility in water. Its chemical structure includes a cyano group (-C≡N) attached to a methacrylic backbone, making it a valuable monomer in the production of various copolymers and resins. The compound is known for its ability to undergo radical polymerization, which is utilized in the synthesis of plastics and coatings. However, it is also recognized for its toxicity and potential health hazards, necessitating careful handling and appropriate safety measures during use. Methacrylonitrile is primarily employed in the manufacture of specialty polymers and as an intermediate in organic synthesis.
