EC number: 926-000-9
CAS number: 1180524-77-9
For pH 4 and pH 7 no abiotic degradation
of the test item was observed in aqueous buffer solutions with
acetonitrile as organic solvent additive (30 % v/v) at 50 °C. For pH 9 a
slight degradation less than 10 % was observed. It can be assumed that
the test item is also stable at 25 °C.
5.2.1 Biodegradation in water:
Within 28 days, a degradation rate of 9
% was determined. The substance is considered to be "Not Readily
5.2.2 / 5.2.3 / 5.3.1
Biodegradation in water and sediment / Biodegradation in soil:
In accordance with REACH Annex XI,
degradation simulation testing in water and/or sediment does not need to
be conducted as from the chemical safety assessment it can be concluded
that there is no risk for the aquatic compartment. There is no waste
water and no introduction of the substance in the aquatic compartment
from manufacture or use of the substance and, therefore, degradation
simulation testing is not necessary.
In accordance with column 2 of REACH
Annex IX, the bioaccumulation in aquatic species study does not need to
be conducted as the substance has a low potential for bioaccumulation as
reflected by the log Kow of 1.4.
An adsorption coefficient (log Koc) in the range of 2.5
to 4.4 was determined at pH 6 and 40°C. The result can be expected to be
equal at 25 °C.
