Overview
D-Glucaric acid, also known as saccharic acid, is a derivative of glucose oxidation. It is a naturally occurring compound found in small amounts in fruits and vegetables. The compound is valued for its chelating and detoxifying properties, making it useful in various industrial and pharmaceutical applications. D-Glucaric acid is commonly produced through the oxidation of glucose or starch. It is available in various forms, including calcium D-glucarate, which is used as a dietary supplement. The compound is biodegradable and considered environmentally friendly, enhancing its appeal in sustainable industrial processes.
Physical and Chemical Properties
D-Glucaric acid is a white crystalline powder with a molecular weight of 210.14 g/mol. It is soluble in water and slightly soluble in ethanol. The compound decomposes at approximately 125-130°C, and its solubility makes it suitable for aqueous formulations. One of the key properties of D-glucaric acid is its ability to form stable complexes with metal ions, acting as a chelating agent. This property is leveraged in industrial applications such as corrosion inhibition and water treatment. The compound is also known for its detoxifying effects, which are utilized in pharmaceuticals and dietary supplements.
Main Applications
D-Glucaric acid is widely used in the food industry as a food additive, particularly in beverages and dairy products, where it acts as a stabilizer and preservative. Its chelating properties make it effective in preventing oxidation and extending shelf life. In the pharmaceutical industry, D-glucaric acid and its salts are used in detoxification therapies and as excipients in drug formulations. The compound is also employed in industrial applications, including detergents and corrosion inhibitors, due to its ability to bind metal ions and reduce scaling.
Safety and Storage
D-Glucaric acid is generally recognized as safe (GRAS) for use in food applications. However, proper handling is recommended to avoid inhalation of dust, which may cause respiratory irritation. The compound should be stored in a cool, dry place away from direct sunlight to maintain stability. For industrial use, safety data sheets (SDS) should be consulted to ensure compliance with local regulations. Personal protective equipment (PPE), such as gloves and masks, may be required when handling large quantities to prevent skin or respiratory exposure.
B2B Procurement Guide
When procuring D-glucaric acid, it is essential to verify the purity and specifications required for your application. Pharmaceutical and food-grade applications demand higher purity levels, typically above 98%. Suppliers should provide certificates of analysis (CoA) to confirm quality. Bulk purchases may offer cost savings, but storage conditions must be considered to prevent degradation. Reliable suppliers with a track record in chemical distribution are preferred. Prices vary based on purity and quantity, with reference ranges commonly between $20-$50 per kilogram.
