Tetramethylsuccinonitrile

6 ppm (rat, 30 hr) Tetramethylsuccinonitrile or TMSN is an organic compound with the formula (C(CH3)2CN)2, classified as a dinitrile, and a colorless and odorless solid derived from 2,2'-azobis-isobutyronitrile, a common radical initiator in the manufacture of PVC: :.

Because PVC is pervasive and can contain TMSN, the safety aspects of this dinitrile has generated interest.

In regards to occupational exposures, the U.S. Occupational Safety and Health Administration and the U.S. National Institute for Occupational Safety and Health have set limits for dermal exposure at 3 mg/m3 over an eight-hour time-weighted average.
