Description of key information

Colorless liquid with an ammonia-like odour, or a yellowish solid material, depending upon the content of different geometric isomers

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
liquid

Additional information

4,4'-Methylenedicyclohexanamine has three geometric isomers which impact the physical state of the substance: trans-trans, cis-cis or cis-trans.

4,4'-Methylenedicyclohexanamine is a clear liquid when the trans-trans isomer content is approximately 20 -25%. It is a yellowish solid melt (non-granular material) when the trans-trans isomer is greater than 50%.
