EC number: 948-069-4
CAS number: -
determined solubility was 9.22 mg/L for double distilled
water and 8.18 mg/L for daphnia medium for the centrifuged
samples. The results obtained with un‑centrifuged
samples vary between 11,6 mg/L and 425 mg/L. As the un‑centrifuged
samples were not obtained under slow‑stirring
conditions, their results were not further taken into
account. Due to technical reasons (facilitating the
handling), 0.1 % v/v (approx. 1 g/L) was used for the
application dose in the definitive test.
each sample, no Tyndall‑effects were observed. (6 sampling
time, 2 media, un-centrifuged and centrifuged)
was considered reached from 43h after temperature reduction.
solubility of the test item in double distilled water and
daphnia M4 medium was determined for un‑centrifuged and
centrifuged samples, respectively (average
of 6 consecutive sampling x 2 replicates):
The water solubility of the test item
was determined under GLP, according to OECD 105 / EU A6 guideline, using
the flask method with slow-stirring approach, in double distilled water
and daphnia medium M4, at 20 ± 0.5 °C with 72h preincubation at
30 ± 0.5 °C . Duplicate test vessels were prepared.
Analytical evaluation was performed
with GC-MS using the test item for external calibration. The method was
validated with satisfactory results regarding linearity, limit of
quantification, accuracy, precision and specificity.
Equilibrium was considered achieved
43h after reduction to test temperature.
The pH-values were measured with
indicator strips. All samples were checked negative for colloidal
dispersed material utilising the Tyndall effect.
solubility (20 °C, pH 7) was determined to be 10.2 mg/L in distilled
water, and 9.9 mg/L in daphnia medium M4.
Slightly soluble. Equilibrium reached from 43 hours.
pH of saturated solution: 7
A fully reliable experimental study,
conducted according to a recognized OECD/EC method and under GLP, is
available. Therefore, it is considered as a key study, and the result is
retained as key data.
