Description of key information

Additional information

PACM (4,4’-methylenebis(cyclohexylamine)) does not possess hydrolysable functional groups (esters, carbamates, epoxides, halomethanes (containing 1-3 halogens), and specific alkyl halides), and thus is expected to be stable in water.


PACM is likely to undergo photolysis in the atmosphere; its degradation constant with hydroxyl radicals was predicted to be 116.5291 x 10-12 cm3/molecule-1s-1(AOPWIN v1.92a).
