Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Phototransformation in air

No data available (not required for REACH)


Due to its chemical structure, diisopropylnaphthalene (DIPN) cannot be hydrolyzed. The structure of the molecule does not contain hydrolysable groups.

Phototransformation in water

Photolytic half life of 2,6-DIPN (used as supporting substance) in distilled water was 16 h using a high pressure mercury lamp as irradiation source. For 2,7-DIPN, a half-life of 6.4 h was determined. In salt water, phototransformation was accelerated (half-life of 2,6 DIPN in 0.5 M NaCl < 4 h).

Phototransformation in soil

No data available (not required for REACH)
