character:

White odorless powder or crystalline solid particles. It has a special sour taste, which is about 1.5 times that of citric acid. Soluble in ethanol (5.76g/100g, 30 ℃), slightly soluble in water (0.63g/100ml, 25 ℃) and ether, very insoluble in chloroform. No hygroscopicity, sublimation above 200 ℃, boiling point 290 ℃ (decomposition), heating to above 230 ℃ to form maleic anhydride, and co boiling with water to form DL malic acid.
