Description of key information

Hydrolysis

The results of the Tier 2 hydrolysis test showed that the substance undergoes hydrolysis at environmentally relevant pH’s (t1/2 = 374 hours (15.6 days) at pH 4, 985 hours (41 days) at pH 7, and 566 hours (23.6 days) at pH 9, at 25°C). The hydrolysis products were identified.

Additional information

In the course of the hydrolysis preliminary test performed at 50°C, significant decomposition was observed at pH 4, 7 and 9. The results of the Tier 2 hydrolysis test showed that the substance undergoes hydrolysis at environmentally relevant pH’s (t1/2 = 374 hours (15.6 days) at pH 4, 985 hours (41 days) at pH 7, and 566 hours (23.6 days) at pH 9, at 25°C). It should be noted that use of the substance as a dyestuff will take place at elevated temperatures within alkaline pH solutions that promote the dyeing process.
