Malic acid CAS 6915-15-7

What is Malic acid CAS 6915-15-7?

Malic acid CAS 6915-15-7 is a 2-hydroxydicarboxylic acid used as a food acidity regulator, pharmaceutical acidulant, and versatile organic intermediate. It appears as a white to almost white solid and is also described as a fundamental metabolite found naturally in apples and other fruits. It is widely used where strong tartness, water solubility, and formulation compatibility are needed.

Specifications

Features

• Strong Acidulant Performance: Malic acid is widely used as an acidulant and is noted for having a stronger apparent acid taste and longer taste retention than citric acid in food applications.
• High Water Solubility: With water solubility reported at 558 g/L at 20 °C, malic acid is suitable for formulations requiring fast dissolution and convenient processing.
• Broad Formulation Utility: The reference page describes malic acid as being used in food, pharmaceutical, and cosmetic products, showing strong versatility across multiple industries.
• Useful Chiral and Synthetic Building Block: The page also identifies malic acid as a versatile synthon for the preparation of chiral compounds and lists it under chemical synthesis and organic building blocks.

Applications

• Food and Beverage Industry: Malic acid is used in soft drinks, dry-mix beverages, puddings, jellies, fruit fillings, hard candies, jams, jellies, and canned fruits and vegetables as an acidulant and flavor enhancer.
• Pharmaceutical Formulations: It is used as a general-purpose acidulant and flavoring agent in pharmaceutical products, including effervescent powders, mouthwashes, and tooth-cleaning tablets.
• Cosmetic Products: Malic acid is used in cosmetic formulations, especially in products marketed with fruit-acid content and anti-aging positioning, although the page notes it is rarely used as the only AHA in a product.
• Chemical Synthesis and Biochemical Research: It is used as an organic building block and is also relevant in biochemical and metabolic studies because the page describes it as an important regulatory metabolite involved in fruit ripening and starch metabolism.
