CAS number: -
Hydrolysis was assessed for the test item and based on the isopropyl
ether constituent of the test item the half-life was determined to be >1
year at pH 4, 7 and 9 and 25°C.
Hydrolysis was assessed for the test item. Assessment
of hydrolytic stability was based on the isopropyl ether component of
the test material only, as this was determined to be the dominate
dissolved component in aqueous solutions originating from lower, more
environmentally relevant nominal saturation concentrations of 1.0
the water solubility testing. In
addition the 2-methylpentane component contained no hydrolysable
functional groups. When
monitoring the sample solutions as equivalent test material
concentration using the total peak area of all dissolved components,
slightly greater than 10% apparent hydrolysis was observed after 120
hours incubation at 50°C (percentages remaining of 88.6%, 83.3% and
81.9% for pH 4, pH 7 and pH 9 respectively). However, this was concluded
to originate from a cumulative reduction in the concentration of a
number of less significant dissolved components present, the
quantification of which was beyond the scope of the method guideline.
