It is stable in neutral medium, easy to produce reversible hydrolysis in hot alkali and lactone when pH returns to neutral, but slow in acid medium.
[dissolution]
It is miscible with water and soluble in methanol, ethanol, ether, acetone, benzene and carbon tetrachloride
Note: it is flammable liquid, and avoid direct contact with fire source.
Toxicity: low toxicity. The oral LD50 of mice was 345 mg / kg.
