Description of key information

The half life of the magnesium methanolate was determined to be T1/2 < 1 min (Hydrolysis as a Function of pH). In all experiments the hydrolysis of magnesium methanolate in buffer solutions (pH4, pH7, pH9) could be observed immediately. Hydrolysis rates of >= 90% within 1 minute reaction time are observed for all samples. Magnesium methanolate hydrolyse into methanol and magnesium hydroxide.

The hydrolysis product methanol is readily biodegradable and the hyrolysis product magnesium hydroxide does not contain any hydrolysable functional groups.


Key value for chemical safety assessment

Half-life for hydrolysis:
1 min
at the temperature of:
20 °C

Additional information

Magnesium methanolate is an extremely strong conjugate base. In contact with water magnesium methanolate reacts to form magnesium hydroxide and methanol:

(CH3O)2Mg + 2 H2O → 2 CH3OH + Mg(OH)2
