Description of key information

The QSAR calculated rate constant for the OH sensitized photodegradation of decamethylenediamine is approximately 74.67E-12 cm3/(molecule * s). At 500,000 OH radicals / cm3 (typical for central Europe), this corresponds to a half-life of 5.2 hours (24-hour days).

Key value for chemical safety assessment

Half-life in air:
5.2 h
Degradation rate constant with OH radicals:
