Stability
|
sensitive to air, moisture, light and heat; storage at temperatures higher than 40°C result in discolouration of the product; hydrolyzes in acidic media, as it is characteristic for acetals, to succinaldehyde (2.4.)
|
|
Solubility
|
soluble in water up to approx. 10%; completely soluble in a range of polar solvents such as methanol, ethanol and propanol
