Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Read across. The vapour pressure of N-C12,14 alkyl-1,3-diaminopropane was determined to be 1.5 mPa at 20°C.

Key value for chemical safety assessment

Vapour pressure:
0.002 Pa
at the temperature of:
20 °C

Additional information

Read across. As a worst case, the vapour pressure is read across from a substance with lower carbon chain distribution within the diamine category. Since the vapour pressure increase with decreasing hydrophobe in a specific homologue, it is a worst case to read across from a substance with lower carbon chain distribution. CAS 90640 -43 -0 consist of mainly 12 and 14 carbons while CAS 7173 -62 -8 consist of mainly C16 and C18.
