Description of key information
At 25 °C, Reactive Brown 49 is stable at pH 4 with half-life period is greater than one year; while at pH 7 has a half-life period of 64.3 h (about 2.7 days) and is unstable at pH 9 with half-life period shorter than one day.
The Reactive brown 49 is not readily or inherently biodegradable.
Reactive Brown 49 can be regarded as little mobile in all three soils in adsorption and desorption test.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
