Q:
What is D-Glucurone CAS 32449-92-6?
A: 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. -
Q:
How does D-glucurone relate to glucuronic acid?
A: D-glucurone is the intramolecular ester of D-glucuronic acid. In aqueous solution the lactone can exist in equilibrium with the open acid form, while the crystalline material is supplied as the stable lactone with CAS 32449-92-6. -
Q:
What are the main applications?
A: It is used in energy drinks and functional beverages, dietary supplements, pharmaceutical hepatoprotective formulations, biochemical research and as an intermediate for glucuronic-acid derivatives. -
Q:
Why is glucuronolactone used in energy drinks?
A: 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. -
Q:
Which grade and packaging are available?
A: 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. -
