Description of key information
Hydrolysis
Hydrolysis of Benzenamine, 4-[(4-aminophenyl)(4-imino-2,5-cyclohexadien-1-ylidene)methyl]-, N-Me derivatives, molybdatesilicates (CAS no. 63647 -35 -8) is predicted using OECD QSAR toolbox version 3.4 (2018) with logKow as the primary descriptor. The estimated half-life of Benzenamine, 4-[(4-aminophenyl)(4-imino-2,5-cyclohexadien-1-ylidene)methyl]-, N-Me derivatives, molybdatesilicates was estimated to be 78.1 days, indicating that it is not hydrolysable.

Hydrolysis
Predicted data for the target chemical Benzenamine, 4-[(4-aminophenyl)(4-imino-2,5-cyclohexadien-1-ylidene)methyl]-, N-Me derivatives, molybdatesilicates (CAS No.68647-35-8) and supporting study from authoritative database for its read across substance were reviewed for the hydrolysis end point which are summarized as below:
In a prediction done by SSS (2018) using OECD QSAR toolbox version 3.4 with logKow as the primary descriptor, hydrolysis of test chemical Benzenamine, 4 -[(4 -aminophenyl)(4 -imino-2,5 -cyclohexadien-1 -ylidene)methyl]-, N-Me derivatives, molybdatesilicates (CAS No.68647 -35 -8) is predicted. The estimated half-life of chemical Benzenamine, 4 -[(4 -aminophenyl)(4 -imino-2,5 -cyclohexadien-1 -ylidene)methyl]-, N-Me derivatives, molybdatesilicates was estimated to be 78.1 days, indicating that it is not hydrolysable.
For the read across chemical fenpyroximate (CAS no. 134098-61-6), the half-life and base catalyzed hydrolysis rate constant of the read across chemical fenpyroximate (CAS no. 134098-61-6) was estimated using structure estimation method. The based catalyzed hydrolysis rate constant of fenpyroximate was determined to be 0.016 L/mol-sec, respectively with a corresponding half-lives of 13 and 1.3 years at pH 7 and 8, respectively.
On the basis of the above results for target chemicalBenzenamine, 4-[(4-aminophenyl)(4-imino-2,5-cyclohexadien-1-ylidene)methyl]-, N-Me derivatives, molybdatesilicates (fromOECD QSAR toolbox version 3.4, 2018) and for its read across substance (from authoritative database HSDB, 2017), it can be concluded that the target chemical Benzenamine, 4 -[(4 -aminophenyl)(4 -imino-2,5 -cyclohexadien-1 -ylidene)methyl]-, N-Me derivatives, molybdatesilicates is not hydrolysable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
