Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Executive summary:

The vapour pressure of the substance Disodium 4,4’-(2,4-dihydroxy-5- hydroxymethyl-1,3-phenylene bis-azo) di- (naphthalene-1-sulfonate) is determined to be 1.48E-33 mm Hg at 25°C which is < 0.0000000000001 mm Hg.

Description of key information

The vapour pressure of the substance Disodium 4,4’-(2,4-dihydroxy-5- hydroxymethyl-1,3-phenylene bis-azo) di- (naphthalene-1-sulfonate) is determined to be 1.48E-33 mm Hg at 25°C which is < 0.0000000000001 mm Hg. This value is equivalent to 1.97E-31 Pascal at 25°C.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

The vapour pressure of the substance Disodium 4,4’-(2,4-dihydroxy-5- hydroxymethyl-1,3-phenylene bis-azo) di- (naphthalene-1-sulfonate) is found to be 1.48E-33 mm Hg at 25°C which is < 0.0000000000001 mm Hg. This value is equivalent to 1.97E-31 Pascal at 25°C.

However due to restriction in above key value field, the value considered for CSR is 0.000000001 Pa. This value indicates that the chemical has extremely low vapour pressure.
