ACETONITRILE (METHYL CYANIDE) Chemical compatibility with O-rings, rubbers, & plastics

Acetonitrile, also known as methyl cyanide, is a colorless, volatile liquid with a slightly sweet odor, represented by the chemical formula CH3CN. It is widely used as a solvent in the pharmaceutical industry, particularly in the synthesis of active pharmaceutical ingredients (APIs) and in chromatography. Acetonitrile is also used in the production of rubber products, plastics, and batteries. It is produced as a byproduct of acrylonitrile manufacture. Acetonitrile is highly flammable and can cause irritation to the eyes, skin, and respiratory system upon exposure. Proper handling and storage are essential to prevent accidents and exposure-related health risks. Personal protective equipment (PPE), proper ventilation, and adherence to safety guidelines are necessary when working with acetonitrile. Always refer to the material safety data sheet (MSDS) for detailed safety and handling instructions.
