CAS 91628-87-4

Acrylonitrile-1-13C, with the CAS number 91628-87-4, is a stable isotopic variant of acrylonitrile, which is a colorless, volatile liquid with a characteristic odor. The presence of the carbon-13 isotope in its structure indicates that one of the carbon atoms in the acrylonitrile molecule is a heavier isotope, which is often used in various analytical techniques, including nuclear magnetic resonance (NMR) spectroscopy and isotopic labeling studies. Acrylonitrile itself is primarily used in the production of polymers and fibers, such as polyacrylonitrile, which is utilized in textiles and as a precursor for carbon fibers. The compound is known for its reactivity, particularly in polymerization reactions, and it can undergo various chemical transformations, including nitration and hydrolysis. Safety considerations are important, as acrylonitrile is toxic and potentially carcinogenic, necessitating proper handling and storage protocols in laboratory and industrial settings.
