D-Glucose Powder Monohydrate

D-Glucose Powder Monohydrate, also known as D-(+)-Glucose Monohydrate or dextrose monohydrate, is a naturally occurring monosaccharide and carbohydrate in crystalline powder form. Its chemical formula is C6H12O6·H2O, with a molecular weight of approximately 198.17 g/mol due to the inclusion of one water molecule (monohydrate).

Key properties:

Appearance: White to off-white crystalline powder or colorless crystals

Odor: Odorless

Solubility: Freely soluble in water; sparingly soluble in ethanol

Melting point: Around 83 °C

Density: Around 1.54 g/cm³

pH (1% aqueous solution): Approximately 5.9 to 7

Optical activity: [α]20/D +52.5 to +53.3° (indicating the D-form)

D-Glucose monohydrate is widely used as a supplement in food, pharmaceuticals, and biochemistry applications. It serves as an energy source in cell culture and biological studies, and as a standard in analytical chemistry. It is obtained industrially by enzymatic hydrolysis of starch followed by purification and crystallization.

In summary:

Chemical formula: C6H12O6·H2O

Form: White crystalline powder, odorless

Solubility: Highly soluble in water

Common uses: Nutritional supplement, pharmaceutical ingredient, cell culture carbon source, analytical reagent

This form of glucose is stable, pure, and widely employed in scientific, medical, and industrial applications.
