Tetramethylsuccinonitrile

Tetramethylsuccinonitrile (TMSN) is a chemical compound that is primarily used in the chemical industry as a catalyst and intermediate in the production of other chemicals. It is a white, crystalline solid with a faint, sweet odor.

Chemical Properties

Tetramethylsuccinonitrile is a nitrile compound, which means it contains a carbon-nitrogen triple bond. It has the chemical formula (CH3)2C(CN)2 and a molecular weight of 140.19 g/mol. It is soluble in water, alcohol, and most organic solvents.

Production

Tetramethylsuccinonitrile is produced through the condensation reaction of acetonitrile with formaldehyde in the presence of a base such as sodium hydroxide.

Uses

Tetramethylsuccinonitrile is used as a catalyst in the production of polymers and resins. It is also used as an intermediate in the synthesis of other chemicals, including pharmaceuticals and dyes.

Health Effects

Exposure to tetramethylsuccinonitrile can cause irritation to the eyes, skin, and respiratory system. Long-term exposure can lead to neurological damage, including neuropathy and neurodegeneration. It is considered a hazardous substance and should be handled with care.

Safety

Tetramethylsuccinonitrile should be stored in a cool, dry place away from heat and open flame. It should be handled with gloves and protective eyewear. In case of exposure, the affected area should be washed with water and medical attention should be sought.
