Chirality Grade Lactic Acid is a high-purity biodegradable organic acid optimized for chiral synthesis. It offers excellent chemical stability, enantiomeric purity, and environmental benefits, making it ideal for pharmaceutical, agrochemical, and specialty chemical applications.
Product Overview
Chirality grade lactic acid (L(S)-2-hydroxypropanoic acid) is a high-purity lactic acid produced by modern fermentation refinement techniques, using corn stover or corn starch as the raw material. It is a colorless, clear, viscous liquid with a mild acidic taste and excellent hygroscopicity. Its aqueous solution is acidic, and it can mix with water, ethanol, or ether, but is insoluble in chloroform.
Product Features
- No Unpleasant Odor:The product has a mild, slightly acidic taste without any undesirable odor.
- Strong Hygroscopicity:It has significant moisture-absorbing properties, suitable for various industrial needs.
- Good Solubility:It can mix with water, ethanol, or ether, making it adaptable to a wide range of chemical processes.
Applications
- Chemicals and Biochemical Industries:Widely used as a raw material in the production of fine chemicals and biochemicals.
- Food Industry:Used as a flavoring agent and acidulant in food processing.
- Pharmaceutical Industry:Acts as an acidifier or buffer in pharmaceutical processes.
- Electroplating and Other Industries:Key applications in electroplating, plastics, and synthetic resins.
