Description of key information

Half-life for reaction with photochemically-produced hydroxyl radicals: estimated to be 23.0 days.

Key value for chemical safety assessment

Half-life in air:
23 d
Degradation rate constant with OH radicals:
0 cm³ molecule-1 d-1

Additional information

The stability of trimethyl benzene-1,2,4-tricarboxylate in the atmosphere was calculated using the computer program AOPWIN (v 1.92). It is predicted that the substance will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air is estimated to be 23.0 days.

The overall degradation rate constant with OH radicals is estimated to be equal to 6.025E-8 cm3/(molecule-day).
