Description

Glucuronolactone is a vital organic compound and a key intermediate in the biosynthesis of ascorbic acid. Its primary commercial value lies in its role as a versatile building block for pharmaceuticals, nutraceuticals, and high-purity biochemicals. This product is essential for manufacturers in the pharmaceutical, dietary supplement, and cosmetic industries seeking reliable, high-quality raw materials for synthesis and formulation.

Application

• Pharmaceutical Synthesis: A critical precursor in the production of ascorbic acid (Vitamin C) and various glycosaminoglycans.
• Dietary Supplements & Nutraceuticals: Used as an ingredient in energy-boosting and detoxification formulations, often marketed for liver support.
• Cosmetic & Personal Care: Incorporated into skincare products for its purported antioxidant and skin-brightening properties.
• Biochemical Research: Serves as a standard and reagent in enzymatic studies and metabolic pathway analysis.
• Food & Beverage Additive: Employed as a processing aid and a component in functional food products.
• Veterinary Pharmaceuticals: Used in formulations for animal health, similar to its human pharmaceutical applications.

Quality Control

Our Glucuronolactone is manufactured under strict quality management systems. We provide material that meets or exceeds Food Chemical Codex (FCC) and pharmaceutical-grade standards, with specifications tailored for high-purity applications. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, available upon request to ensure full traceability and compliance for your projects.

Storage

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