Description
Product name: Malic acidSynonyms: Hydrozybutanedioic acid, DL-Malic acid
Molecular formula: C4H6O5
Molecular weight: 134.09
CAS number: 617-48-1
Assay: 99.5%
Characteristic: white crystals or white crystalline powder, soluble in water, alcohol and other organic solvent. Its aqueous solution is acidic
Functions and usage:
It is an important four-carbon atoms chiral pool. It is mainly used in many fields including chiral pharmaceuticals, chiral additives and chiral auxiliaries. It is used as chiral pool of chiral synthesis in pharmaceutical and food industries. As an optically active organic acid, it is insubstitutable in asymmetry synthesis of some chiral compounds.
DL-Malic acid can be used as an acidulant in cool drinks (including lactobacillus drinks, milk drinks, carbonated drinks, cola), frozen foods (including sherbet and ice cream), processed foods (including wine and mayonnaise). DL-Malic acid is used as color-keeper and antiseptic of juice. DL-Malic acid is also used as emulsion stabilizer of egg yolk. DL-Malic acid also can be used as pharmaceutical intermediate, cosmetic, rinse, metal cleaner, buffering agent, retarder in textile industry, fluorescent whitening agent of polyester fibre.
L-Malic acid can be added into composite amino acid injection, directly participating the metabolic cycle of organism-Krebs cycle. L-Malic acid can reduce the metabolic loss of amino acid and can compensate hypohepatia, cure uremia and hypertension, and weaken the damage of anticancer drug to normoblasts. L-Malic acid is also used in skin disinfector, air depurative and deodorizer.
