Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 predicted pKa value is outside the pH range 0 to 13, considered relevant to the general assessment of potential dissociation of the test item in water.
Key value for chemical safety assessment
- pKa at 20°C:
- 15
Additional information
A computer estimation for the dissociation constant in water of Cis-hex-3-en-1-ol (LFA) was produced using the I-Lab 2.0 prediction software from Advanced Chemistry Development Inc. The predicted pKa was 15 for the alcohol functional group. The value is outside the environmentally relevant pH range of 0 to 13.
Experimental testing according to Method 112 of the OECD Guidelines for Testing of Chemicals, 12 May 1981, was considered not applicable due to the extremely high pKa estimated, which surpasses the pH values that can be accurately determined with a glass electrode.
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.
