Acetonitrile (CAS 75-05-8)：Safety and Health Hazards
Small amounts of acetonitrile are relatively toxic, but in large doses, it can be converted into hydrogen cyanide, which is toxic. Since it takes time for the body to metabolize acetonitrile to cyanide, its toxic effects are delayed. The eyes, throat, lungs, and nose can become irritated.
Its long-term effects are thyroid enlargement, headaches, numbness, lack of appetite, dizziness, weakness, and tremors. Scientists observe animal reproductive problems, including birth defects and low birth weights. Acetonitrile can affect the liver, lungs, central nervous system, and kidneys for a long time.
