(2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.COA of Formula: C6H14O6

An Improved Synthesis of 4-O-Benzoyl-2,2-difluorooleandrose from L-Rhamnose. Factors Determining the Synthesis of 2,2-Difluoro-Carbohydrates from 2-Uloses was written by Barrena, M. Isabel;Matheu, M. Isabel;Castillon, Sergio. And the article was included in Journal of Organic Chemistry in 1998.COA of Formula: C6H14O6 This article mentions the following:

4-O-Benzoyl-2,2-difluorooleandrose I has been synthesized from L-rhamnose via DAST difluorination of ulose II followed by chemoselective etherification. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0COA of Formula: C6H14O6).
