1,1′-Azobis(cyclohexanecarbonitrile) or ACHN is a
radical initiator
In chemistry, radical initiators are substances that can produce radical species under mild conditions and promote radical reactions. These substances generally possess weak bonds—bonds that have small bond dissociation energies. Radical i ...

[ The molecular formula is NCC6H10N=NC6H10CN. It is a white solid that is soluble in aromatic solvents.]
ACHN has a 10-hour half-life
Half-life (symbol ) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable at ...
