Description of key information
Hydrolysis:
The half life of hydrolysis of test chemical Trisodium [2-[[α-[[2-hydroxy-5-sulpho-3-[(2,5,6-trichloro-4-pyrimidinyl)amino]phenyl]azo]benzyl]azo]-5-sulphobenzoato(5-)]cuprate(3-) (CAS no. 70161 -20 -5) was estimated by using OECD QSAR tool box v3.4 considering seven closest read across chemicals with log Kow as primary descriptor. The half life of test chemical Trisodium [2-[[α-[[2-hydroxy-5-sulpho-3-[(2,5,6-trichloro-4-pyrimidinyl)amino]phenyl]azo]benzyl]azo]-5-sulphobenzoato(5-)]cuprate(3-) was estimated to be 151.27 days. On the basi s of this half life value it is concluded that this test chmeical is not hydrolysable.
