Description of key information

Estimation based on the chemical structure.
General Physical Chemistry, Schering AG, Berlin. Study report No. A01734 (APC 88/00), dated 2000-10-10.
Result: Mesterolone is expected to be hydrolytically stable in the pH region 4 to 9.

Key value for chemical safety assessment

Additional information

The test substance molecule and all of its functional groups belong to a class of substances that are generally resistant to hydrolysis, e.g.:

alkanes, alkenes, alkynes, benzenes/biphenyls, polycyclic aromatic hydrocarbons, heterocyclic polycyclic aromatic hydrocarbons, halogenated aromatics, aromatic nitro compounds, aromatic amines, alcohols, phenols, glycols, ethers, aldehydes, ketones, carboxylic acids, sulfonic acids

(for reference see: Lyman, W. J.; Reehl, W. F.; Rosenblatt, D. H.; Handbook of Chemical Property Estimation Methods, McGraw-Hill New York 1982, p. 7-4).

Therefore, mesterolone is to be considered hydrolytically stable in the relevant pH region 4 - 9.
