Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The half-lives of 3-(3-isopropenylphenyl)butanal were determined to be 536 hours (pH 4), 405 hours (pH 7) and 392 hours (pH 9) according to a study performed in line with OECD Guideline 111.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 405 h
- at the temperature of:
- 20 °C
Additional information
Hydrolysis rates at different pH values have been determined by the method described in the OECD Guideline No. 111. Results fit in with a pseudo-first order reaction. The half-times are 400-600 hours at 20ºC. Results may be disturbed by the easy oxidizability of the test substance.
The read-across is considered to be suitable based on the structural and 'mechanistic action' similarities between the target substance (3-(3-isopropenylphenyl)butanal) and source substance (3-(3-isopropylphenyl)butanal) and their similar physico-chemical and environmental fate properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
