CH33CNH3

CH33CNH3, more commonly known as propionitrile, is an organic compound with the chemical formula C3H5N. It is a nitrile, characterized by the presence of a cyano group (-C≡N). Propionitrile is a colorless liquid at room temperature and pressure with a distinctive, somewhat pungent odor. It is soluble in water and many organic solvents.

The synthesis of propionitrile can be achieved through various methods, including the dehydration of propionamide or the reaction of ethyl halide with a cyanide salt. Industrially, it is often produced by the ammoxidation of propane. Propionitrile serves as a precursor in the synthesis of various chemicals, including pharmaceuticals, pesticides, and polymers. Its cyano group can undergo a range of chemical transformations, making it a versatile intermediate in organic synthesis. For example, it can be hydrolyzed to propionic acid or reduced to propylamine.

Propionitrile is flammable and should be handled with appropriate safety precautions. Exposure can cause irritation to the skin, eyes, and respiratory tract. It is considered moderately toxic.
