Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Estimation of the acid base properties based on the chemical structure.
Analytical Development Physical Chemistry, Schering AG Berlin. Study report No. A11833 (ADP 2003_007), dated 2003-01-07.
Result: Mesterolone can be considered as a neutral molecule in the pH range 2 to 10, which is of relevance for biological systems.
Key value for chemical safety assessment
Additional information
Except for a aliphatic hydroxy group, mesterolone does not contain any functional group, which can be protonated or deprotonated significantly in aqueous solution.
For the aliphatic hydroxy group a pKa of 15.1 was calculated with the computer program ACD/pKa DB.
Therefore mesterolone is to be considered a neutral molecule in the pH range 2 ¿ 10, which is of relevance for aqueous biological systems.
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.
