- Justification for type of information:
- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
In aqueous systems Octanoic acid, compound with dicyclohexylamine (1:1) is hydrolytically very unstable so that in aqueous solution a rapid decomposition to the educts can be observed.The substance will rapidly dissociate to octanoic acid and dicyclohexylamine. Therefore Octanoic acid, compound with dicyclohexylamine (1:1) is not stable at “standard” testing conditions representative for human and environmental exposure. Hence, it is fully justified to apply the read-across methodology by use of the respective data from the breakdown/decomposition products to describe the (eco)toxicological behaviour of the substance to be registered.
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
Source: octanoic acid, dicyclohexylamine
Target: Octanoic acid, compound with dicyclohexylamine (1:1)
3. ANALOGUE APPROACH JUSTIFICATION
The corresponding breakdown products of Octanoic acid, compound with dicyclohexylamine (1:1) were identified by Ultra Performance Liquid Chromatography - tandem Mass Spectrometer (UPLC-MS) as Octanoic acid and Dicyclohexylamine.
Further evaluation of the hydrolysis time demonstrated that in aqueous solution the decomposition time is smaller than 8 minutes.
