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

D-Glucurone CAS 32449-92-6 is the lactone form of D-glucuronic acid, commonly called D-glucuronolactone or glucuronolactone. It has the molecular formula C6H8O6 and is supplied as a white crystalline powder.

How is D-Glucurone related to D-glucuronic acid?

It is the cyclic ester formed from D-glucuronic acid by internal dehydration, which makes it more stable as a dry solid. In water it slowly hydrolyzes back toward the open acid form.

Why is D-Glucuronolactone used in energy drinks and beverages?

It is a water-soluble ingredient often formulated with taurine, caffeine, and B vitamins in energy and functional beverages. In product development it is used for its identity as glucuronolactone and its compatibility with clear, acidic beverage systems.

What food or pharmaceutical quality specifications apply?

Typical specifications include assay, melting point around 170-176 C, specific rotation about +18 to +20 degrees, low loss on drying, low ash, and controlled heavy metals. Food and pharma grades may differ in documentation and impurity limits.

What solubility and handling points should formulators know?

D-Glucurone is readily soluble in water but only sparingly soluble in alcohol, and aqueous solutions slowly hydrolyze. Store it sealed in a cool, dry place to protect powder flow and crystalline appearance.

Product Description

D-Glucurone, CAS 32449-92-6, also called D-glucuronolactone, is the lactone form of D-glucuronic acid.

Synonyms: D-Glucuronolactone; Glucuronolactone; D-Glucurono-6,3-lactone; Glucuronic acid lactone; D-Glucuronic acid gamma-lactone.

CAS: 32449-92-6.

It has a molecular weight of 176.12 g/mol and is supplied as a white crystalline powder.

It has an assay of 98.5–102.0% and a melting point of about 170–176 °C.

It is readily soluble in water and sparingly soluble in alcohol, and aqueous solutions slowly hydrolyze.

It is widely used as a nutritional additive in energy drinks to boost energy, improve alertness and reduce muscle fatigue.

It is often formulated with taurine, caffeine and B vitamins in clear, acidic functional beverages.

It is used as a raw material for liver detoxification and hepatoprotective pharmaceutical products.

It is used in dietary supplements as a precursor to chondroitin and to support immune function.

It is used as a nutritional enhancer in various processed foods.

The cyclic ester form is more stable as a dry solid than the open acid form.

Food and pharma grades may differ in documentation and impurity limits.

Confirm appearance, identification, assay, melting point, specific rotation, solubility, loss on drying, ash, heavy metals, arsenic, lead, clarity and solution color.

Store in a cool, dry, well-ventilated area away from direct sunlight and moisture.

Keep containers tightly closed, as aqueous solutions slowly hydrolyze and powder flow can be affected by humidity.

Confirm packaging with the requested quantity and destination requirements.
