Isophthalonitrile is an organic compound with the formula C₆H₄(CN)₂. Two other isomers exist, phthalonitrile and terephthalonitrile. All three isomers are produced commercially by ammoxidation of the corresponding xylene isomers. Isophthalonitrile is a colorless or white solid with low solubility in water.[1] Hydrogenation of isophthalonitrile affords m-xylylenediamine, a curing agent in epoxy resins and a component of some urethanes.

Safety

LD50 (rat, oral) is 288 mg/kg.

gollark: An interesting question.

gollark: I stuck a self-sustaining triple fusion reactor unit inside one.

gollark: You can compress an infinite amount of volume into the 13x13x13 space inside one block.

gollark: Compact Machines exists.

gollark: Depends, sometimes it's *not*.
