- Degradation rate constant with OH radicals:
- 0 cm³ molecule-1 s-1
Additional information
There is no specific data on the substance. Read-across to the properties of Hexanoic acid, 3,5,5-trimethyl-, 1,1'-[2-ethyl-2-[[(3,5,5-trimethyl-1-oxohexyl)oxy]methyl]-1,3-propanediyl] ester (EC 613-848-7, CAS65870-94-2) is applicable based on the similarity in structure and physico-chemical properties.
The justification for read-across is presented in Section 13 Assessment reports- Read-across justification.
Based on an estimation using SRC AOP v1.92 with smiles notation, the analogue substance is susceptible to indirect photodegradation in air. The estimated half time for the reaction with OH-radicals is 0.466 days (24 hr day; OH-concentration 1.5E+06 OH/cm³).
