Description of key information

Hydrolysis:

The half life of hydrolysis of test chemical 3-methyl-6-[(4-methylphenyl)amino]-3H-naphtho[1,2,3-de]quinoline-2,7-dione (CAS no. 81 -39 -0) was estimted by using OECD QSAR tool box v3.3 by considering five closest read across chemicals with log Kow as primary descriptor. The half life of hydrolysis of test chemical 3-methyl-6-[(4-methylphenyl)amino]-3H-naphtho[1,2,3-de]quinoline-2,7-dione was determined to be 132.885 days. On the basis of half life value it can be concluded that this test chemical is not  hydrolysable.
