Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Substance decomposes before boiling (OECD 103). Because of instability of the target substance, the boiling point of 2-methylpropanol is used as a key value in CSA.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 108 °C
Additional information
Boiling point was determined by using differential scanning calorimetry according to the guideline OECD 103, and in accordance with GLP. The boiling point could not be determined as substance decomposed before boiling.
This substance is hydrolytically unstable (half-life <10 minutes, Brekelmans 2013). When it comes in contact with water or moisture a complete hydrolysis will take place with no significant reaction products other than 2 -methylpropanol and ethyl acetoacetate and insoluble hydrated titanium oxides.
Because of rapid hydrolysis, the CSA concentrates on the most hazardous degradation product which is 2 -methylpropanol. The read-across data on the boiling point of 2 -methylpropanol; 108 deg. Celsius released from the substance is used as a key value in exposure assessment (peer-reviewed secondary source, Lide D. R. 2008).
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.
