Description

D-Glucuronic Acid Lactone is a vital organic compound and a key intermediate in biochemical pathways. It serves as a crucial precursor for the synthesis of ascorbic acid (Vitamin C) and various glycosaminoglycans, making it indispensable for research and industrial biosynthesis. This high-purity lactone is essential for manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and cosmetic industries, where it is used to develop active ingredients, stabilizers, and detoxifying agents.

Application

• Pharmaceutical Intermediate: A critical starting material in the chemical and enzymatic synthesis of Vitamin C (L-ascorbic acid) and its derivatives.
• Biochemical Research: Used as a substrate or standard in studies of glucuronidation pathways, liver detoxification enzymes (UDP-glucuronosyltransferases), and carbohydrate metabolism.
• Nutraceutical & Dietary Supplements: Incorporated into formulations for its role in supporting the body's natural detoxification processes and connective tissue health.
• Cosmetic Ingredients: Employed in skincare products for its moisturizing properties and as a precursor to hyaluronic acid analogs.
• Food Science: Investigated for use as a natural acidulant, preservative, or functional food additive.
• Chemical Synthesis: Serves as a chiral building block for the production of more complex sugars, glycoconjugates, and specialty chemicals.

Quality Control

Our D-Glucuronic Acid Lactone is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and research applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
