'''Galactitol''' also known as '''dulcitol''' is a sugar alcohol, the reduction product of galactose, having the formula '''C<sub>6</sub>H<sub>14</sub>O<sub>6</sub>'''.

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
*Filler for medical capsules

==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 or glass bottle will suffice.

===Disposal===
No special disposal is required. Discard it as you wish.
