Galactitol also known as dulcitol is a sugar alcohol, the reduction product of galactose, having the formula C₆H₁₄O₆.

It is commonly encountered as the d isomer, D-galactitol.

Properties

Chemical

Galactitol can be nitrated using a nitrating mixture to galactitol hexanitrate.

Physical

Galactitol is a colorless crystalline solid, soluble in water, but insoluble in halocarbons and hydrocarbons.

Availability

It is sometimes available as sweetener, though not as common as other sugar alcohols.

Can be bought from chemical suppliers.

Preparation

Can be produced via reduction of galactose.

Galactitol is best bought than made.

Projects

• Sweetener
• Galactitol hexanitrate

Handling

Safety

Galactitol has low toxicity, though it's not commonly used as sweetener as it's more expensive than other sugar alcohols.

Galactitol is accumulates in galactokinase deficiency.

Storage

No special storage is required, a plastic bottle will suffice.
