L-Aspartic acid appears as white crystals or crystalline powder with a slightly acidic taste. Dissolved in boiling water, slightly soluble in water (0.5%) at 25 ℃, easily soluble in dilute acid and sodium hydroxide solutions, insoluble in ethanol and ether, decomposed at 270 ℃, with an isoelectric point of 2.77. Its specific rotation depends on the solvent dissolved.

L-Aspartic acid is used as an electrolyte supplement for amino acid infusion, inorganic ion supplements such as potassium and calcium, and fatigue recovery agents. Potassium magnesium aspartate injection or oral solution is used for arrhythmia, premature beats, tachycardia, hypokalemia, hypomagnesemia, heart failure, myocardial infarction, angina pectoris, hepatitis, cirrhosis and other diseases caused by cardiac glycoside poisoning.
