Description of key information

The QSAR calculated rate constant for the OH sensitized photodegradation of isophorone diamine is approximately 8.47E-11 cm3/(molecule * s). At 500,000 OH radicals / cm3 (approximate 24-hour mean in central Europe), this corresponds to a half-life of 4.5 hours.

Key value for chemical safety assessment
