Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Endpoint:
dissociation constant
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is hydrolytically unstable (half-life less than 12 hours)

Description of key information

Not applicable.

Key value for chemical safety assessment

Additional information

According to the Annex IX Standard Information Requirements of Regulation (EC) No 1907/2006 (REACH), the dissociation constant study does not need to be conducted as the substance is hydrolytically unstable (Please refer to IUCLID section 5.1.2). The study on hydrolysis was waived as the substance was determined to be readily biodegradable (Please refer to IUCLID section 5.2.1). Data from the water solubility study clearly shows, that the substance is hydrolitically not stable. Thus, it is technically not feasible and scientifically not justified to perform the study on the dissociation constant.
