Description of key information
Hydrolysis:
The hydrolytic half-life of 4,4'-carbonimidoylbis[N,N-diethylaniline] monohydrochloride was estimated to be 156.41 days, indicating that it is
very negligibly hydrolysable.
Additional information
Hydrolysis:
Predicted data for the test substance4,4'-carbonimidoylbis[N,N-diethylaniline] monohydrochloride and its structurally related substance were reviewed for hydrolysis endpoint and are presented below as weight of evidence approach:
Hydrolysis of4,4'-carbonimidoylbis[N,N-diethylaniline] monohydrochloridewas predicted using OECD QSAR toolbox version 3.3 (2017). The
hydrolytic half-life of 4,4'-carbonimidoylbis[N,N-diethylaniline] monohydrochloride was estimated to be 156.41 days. This value indicates that
4,4'-carbonimidoylbis[N,N-diethylaniline] monohydrochloride very negligibly hydrolysable.
The hydrolysis rate conatant of structuralyy related chemical 4-[(4-dimethylaminophenyl)-phenylmethylidene]cyclohexa-2,5-dien-1-ylidene]-dimethylazanium chloride (CAS 569 -64 -2) estimated is 4.31e-11 cm3/mol/sec, as this hydrolysis rate constant is very less this chemical shows negligible hydrolysis and it is also supported by data obtained from authoritative database ( HSDB) that this chemical lack hydrolyzable functional group and does not undergo hyrolysis.
Considering the above summarised data and by applying weight of evidence approach it can be concluded that the substance
4,4'-carbonimidoylbis[N,N-diethylaniline] monohydrochloride is very negligibly/ slowly hydrolysable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
