L-Aspartic acid
CAS No.56-84-8
Alias：L-Aspartic acid L-ASPARTIC ACID; L-Aspartic acid Pharmaceutical grade 99%; L-Ascorbic acid, 98.5+%, LOW METALS CONTENT.
Molecular formula：C4H7NO4
Molecular weight：133.1
Structural formula：
1. Performance and use:White crystal or crystalline powder, slightly acidic taste. Soluble in boiling water, slightly soluble in water at 25℃(0.5%), easily soluble in dilute acid and sodium hydroxide solution, insoluble in ethanol, ether, heated to 270℃ decomposition, isoelectric point 2Chemicalbook.77, its specific rotation is related to the solvent dissolved. In acid solution it is right-spin, in alkali solution it is left-spin, and in aqueous solution it is right-spin.
Used as an electrolyte supplement in amino acid infusions, inorganic ion supplements such as potassium and calcium, and fatigue recovery agents. Potassium and magnesium aspartate injection or oral solution is used for cardiac arrhythmia and premature beats caused by cardiac glycoside poisoning, tachycardia Chemicalbook tachycardia, hypokalemia, hypomagnesium, heart failure, myocardial infarction, angina pectoris, hepatitis, cirrhosis of the liver and other disorders. Low toxicity, the product is not diluted for injection, renal insufficiency and atrioventricular block with caution.
It can be used as ammonia detoxifier, liver function promoter, fatigue recovery agent and other medicines, food additives and additives for various cool drinks, also can be used as biochemical reagents, culture medium and intermediates for organic synthesis.
It can be used as synthetic sweetener, used in the treatment of heart disease, used as liver function promoter, ammonia detoxifier, fatigue eliminator and amino acid infusion components, etc.
Nutritional supplements, flavouring and aroma enhancers. It is added to various kinds of refreshing beverages. Used as ammonia detoxifier, liver function promoter, fatigue recovery agent.
Used in biochemical research, as fatigue recovery agent, ammonia detoxifier, clinical diagnostic agent.
Main neurotransmitter, causing rapid synaptic excitation.
