D-Glucose Powder Anhydrus purified

D-Glucose Powder Anhydrous Purified is a form of glucose without the water molecule found in the monohydrate form. It appears as a white or colorless crystalline powder that is odorless and sweet in taste. Its chemical formula is C6H12O6, with a molecular weight of approximately 180.16 g/mol, compared to 198.17 g/mol for the monohydrate due to absence of water.

Key properties of anhydrous D-glucose include:

Appearance: White crystalline powder or colorless crystals

Odor: Odorless

Solubility: Freely soluble in water, sparingly soluble in ethanol

Melting point: Approximately 146 °C

Density: About 1.54 g/cm³

pH (0.5 molar aqueous solution): Around 5.9

Optical rotation: [α]20/D +52.5 to +53.3°

This form is more stable and has a longer shelf life than the monohydrate but tends to absorb moisture from air, converting back to the monohydrate form if not stored properly. It is produced industrially by dehydration of glucose monohydrate through drying or crystallization methods.

Common uses include:

Energy source in cell culture and biochemical applications

Ingredient in pharmaceuticals and food products

Analytical reagent and standard in laboratories

Purified anhydrous D-glucose is preferred where moisture sensitivity is critical or for precise analytical purposes.

Summary:

Chemical formula: C6H12O6 (no water of crystallization)

White crystalline powder, odorless, sweet

Freely soluble in water; melting point ~146 °C

More stable than monohydrate but hygroscopic

Applications: Pharmaceutical, biochemical, food, analytical reagent

This purified anhydrous glucose provides a reliable, moisture-free source of glucose for various scientific and industrial needs.
