L-(-)-Malic Acid CAS 97-67-6

What is L-(-)-Malic Acid CAS 97-67-6?

L-(-)-Malic Acid CAS 97-67-6 (also named 2-hydroxysuccinic acid) is a natural chiral organic acid with an asymmetric carbon atom. It appears as white crystalline or crystalline powder with strong hygroscopicity, good solubility in water and ethanol, and a fresh, pleasant sour taste. It widely exists in nature and is widely used in food, chemical synthesis, and pharmaceutical fields.

Specification

Feature

• Physical Form: White crystalline powder with colorless crystals.
• Good Solubility: Highly soluble in water, ethanol, methanol, propanol, and ether; almost insoluble in benzene.
• Pleasant Sourness: Provides mild, persistent, and natural fruit-like acidity.
• Strong Hygroscopicity: Good moisture absorption property for special formulation needs.
• Chiral Purity: Natural L‑configuration, suitable for chiral synthesis and food applications.

Application

• Food Acidulant: Used as food acidity regulator, flavoring agent, and preservative; can replace 80% citric acid, ideal for jelly and fruit-based foods.
• Food Color Protection: Helps maintain natural color of fruits and used in pectin extraction.
• Fermentation & Brewing: Promotes yeast growth and used in salt‑free soy sauce and vinegar production.
• Chemical Synthesis: Used as raw material for esters, complexing agent, and chiral synthetic building block.
• Pharmaceutical Intermediate: Used as amino acid protection reagent, chiral drug synthesis substrate, and enzyme detection material.
