Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. Since, N,N-dimethyl-p-toluidine is a liquid, the Henry's Law Constant's value obtained was very high 9580 Pa-m3/mole at 25 deg C indicating that this substnace is volatile in nature.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
9 580
at the temperature of:
25 °C
