Description of key information

The QSAR determination of the Henry's Law Constant for N-isopropyl-N'-phenyl-p-phenylenediamine using the model HENRYWIN included in the Estimation Program Interface (EPI) Suite v4.11 revealed a value of 0.000146 Pa*m³/mol at 25°C for the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
