Description

D-Saccharic Acid 1,4-Lactone is a naturally occurring organic compound and a derivative of glucaric acid. This versatile lactone serves as a key intermediate and functional ingredient in several high-value industries, prized for its chelating and acidifying properties. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and food sectors for applications ranging from mineral absorption to pH control.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and as a precursor for various therapeutic agents.
• Nutraceutical & Dietary Supplements: Employed as a mineral chelator to enhance the bioavailability of calcium, magnesium, and other essential minerals.
• Food & Beverage Additive: Functions as a natural acidulant, pH regulator, and sequestrant in food processing and beverage production.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies, particularly those involving glucuronidase.
• Cosmetic Formulations: Incorporated into skincare products for its mild exfoliating and chelating properties.
• Industrial Chelating Agent: Used in water treatment and cleaning formulations to bind metal ions and prevent scale formation.

Quality Control

Our D-Saccharic Acid 1,4-Lactone is produced and tested under a strict quality management system. We offer grades suitable for various applications, including Food Grade (FCC) and high-purity Pharmaceutical grades. Every batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles to ensure compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may lead to clumping or hydrolysis.
