What is D-Glucurone CAS 32449-92-6?

D-Glucurone, also known as glucuronolactone, is the cyclic lactone form of D-glucuronic acid. It is a white crystalline powder used in pharmaceutical, biochemical, dietary-supplement and functional-beverage applications.

What are the main applications?

It is used in energy drinks and functional beverages, dietary supplements, pharmaceutical hepatoprotective formulations, biochemical research and as an intermediate for glucuronic-acid derivatives.

Why is glucuronolactone used in energy drinks?

It is included as a carbohydrate-related ingredient associated with normal energy metabolism and detoxification support. Formulators should use a grade, purity and dosage consistent with local food and beverage regulations.

Which grade and packaging are available?

This listing covers pharmaceutical and biochemical grade. It is supplied in 1 kg aluminum-foil bags or 25 kg drums, with custom packaging available on request.

How should D-glucurone be stored and handled?

Store in tightly closed containers in a cool, dry, ventilated area away from moisture, heat and incompatible materials. Use dust-control measures and suitable PPE, and follow the safety information for handling and disposal.

Product Description

D-Glucurone, CAS 32449-92-6, also known as glucuronolactone or D-glucurono-6,3-lactone, is the cyclic lactone form of D-glucuronic acid; the EC/EINECS number is 251-053-3.

Synonyms: glucuronolactone; D-glucurono-3,6-lactone; glucuronic acid lactone; D-glucurono-6,3-lactone; glucurolactone.

CAS: 32449-92-6.

Molecular formula: C₆H₈O₆.

It is a white to off-white crystalline powder, odorless, soluble in water and slightly soluble in ethanol.

EC number: 251-053-3.

The purity (HPLC) is ≥98% (customizable 99%); the melting point is 160–165 °C.

A 1% solution has a pH of 3.0–4.0; it is stable under normal storage conditions.

In aqueous solution the lactone can exist in equilibrium with the open acid form; the crystalline material is the stable lactone.

It is used in energy drinks and functional beverages and dietary supplements.

It is used in pharmaceutical hepatoprotective formulations and biochemical research.

It is used as an intermediate for glucuronic-acid derivatives.

It is included in functional beverages as a carbohydrate-related ingredient associated with normal energy metabolism and detoxification support.

Confirm assay, appearance, melting point, specific rotation, moisture, residue on ignition, heavy metals, residual solvents and microbial limits.

Store in tightly closed containers in a cool, dry, ventilated area away from moisture, heat and incompatible materials.

Confirm packaging with the requested quantity and destination requirements.

Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.
