Description of key information

MPBPWIN model (version 1.44) which is a quantitative structure-activity model available in EPI Suite version 4.11, was used to estimate the vapour pressure of trans hex-2 -enal. The substance falls within the applicability domain of the model. The vapour pressure for trans hex-2 -enal is estimated at 0.63 kPa

Key value for chemical safety assessment

Vapour pressure:
0.63 kPa
at the temperature of:
25 °C
