Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Hydrolysis:
Half life of hydrolysis of test chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5-dien-1-ylidene)-N-methylmethanaminium chloride ( CAS no. 548 -62 -9) is predicted using OECD QSAR tool box v.3.3 using log kow as primary descriptor. The half life of Hydrolysis of chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5-dien-1-ylidene)-N-methylmethanaminium chloride estimated was 291.447 days at 50 deg. C. By this value it is concluded that this test chemical is expected to show negligible hydrolysis.

Hydrolysis:
Predicted data for target compound N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5-dien-1-ylidene)-N-methylmethanaminium chloride( CAS no.548 -62 -9) from OECD QSAR tool box.v.3.3 and supporting study for its read across chemical were reviewed as follow.
Half life of hydrolysis of test chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5-dien-1-ylidene)-N-methylmethanaminium chloride ( CAS no. 548 -62 -9) is predicted using OECD QSAR tool box v.3.3 using log kow as primary descriptor. The half life of Hydrolysis of chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5-dien-1-ylidene)-N-methylmethanaminium chloride estimated was 291.447 days at 50 deg. C. By this value it is concluded that this test chemical is expected to show negligible hydrolysis.
In a supporting study from authoritative database ( Comptox chemistry Dashboard, 2017) the hydrolysis rate constant of read across chemical 4-[(4-dimethylaminophenyl)-phenylmethylidene]cyclohexa-2,5-dien-1-ylidene]-dimethylazanium chloride 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 hydrolysis.
By considering results of both studies it is concluded that the target chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5-dien-1-ylidene)-N-methylmethanaminium chloride is shows negligible hydrolysis..
