L-(-)-Malic Acid Chemical Properties,Uses,Production

Chemical Properties

clear colourless solution

Uses

The naturally occuring isomer is the L-form which has been found in apples and many other fruits and plants. Selective α-amino protecting reagent for amino acid derivatives. Versatile synthon for the preparation of chiral compounds including κ-opioid rece

Definition

ChEBI: An optically active form of malic acid having (S)-configuration.

Uses

Intermediate in chemical synthesis. Chelating and buffering agent. Flavoring agent, flavor enhancer and acidulant in foods.

Purification Methods

Crystallise S-malic acid (charcoal) from ethyl acetate/pet ether (b 55-56o), keeping the temperature below 65o. Or dissolve it by refluxing in fifteen parts of anhydrous diethyl ether, decant, concentrate to one-third volume and crystallise it at 0o, repeatedly to constant melting point.
