용도

7,7,8,8-Tetracyanoquinodimethane is an electron-acceptor molecule used to form charge-transfer superconductors. It is an effective catalyst used for the ?-chlorination of carboxylic acids using chlorosulfonic acid; the presence of TCNQ suppresses competing free-radical chlorination.

참고

Keep container tightly sealed. Store in cool, dry conditions in well sealed containers. Incompatible with oxidizing agents.
