It is primarily used as an intermediate in the chemical synthesis of other compounds. It is the diastereomer of erythritol. In living things, threitol is found in the edible fungus Armillaria mellea.[2] It serves as a cryoprotectant (antifreeze agent) in the Alaskan beetle Upis ceramboides.[3] See also
