Description of key information

The Hydrolysis rate constant of Benzenaminium, 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphthalenyl)amino]-N,N,N-trimethyl-, chloride is estimated to be 0.0000000002118423 cm3/molecule-sec at half-life of 0.606 hrs. The estimated half-life of the substance indicates that the substance Benzenaminium, 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphthalenyl)amino]-N,N,N-trimethyl-, chloride is rapidly hydrolysable

Key value for chemical safety assessment

Half-life for hydrolysis:
0.606 h
at the temperature of:
25 °C
