Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Valid experimental study according to EU testing method A.6 (column elution method).
General Physical Chemistry, Schering AG, Berlin. Study report No. MA02 (APC 05/97), dated 1997-04-14.
Result: S < 2.8 mg/L at 20°C
Key value for chemical safety assessment
Additional information
The column elution method is based on the elution of the test substance with water from a micro-column, which is charged with an inert support material (quartz), previously coated with an excess of the test substance. After certain time intervals samples are taken and analyzed by HPLC until equilibrium is reached. The concentration of the test substance was below the detection limit of the HPLC method (2.8 mg/L) even after 6 days. Therefore, the solubility of mesterolonacetat in water was stated to be:
S20 < 2.8 mg/L
The pH of the saturated solution in water was 5.4.
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.
