Anwendungen & Verwendung
Verwenden
D-(-)-Lactic acid is a useful biochemical for proteomics research. It is also used in the production of chiral drug and in the chemical synthesis. Lactic acid is used as a reagent in organic synthesis (in the manufacture of adhesives). It is used in the leather, textile, and tanning industries. It may be used as a plasticizer, a catalyst, or an acidifying agent. Lactic acid has even been used as a flavoring agent in the manufacture of tobacco products.
