Dihydroxybutanedioic

Dihydroxybutanedioic is a chemical compound with the formula C4H6O4. It is an organic compound containing two hydroxyl groups attached to a butanedioic acid molecule. This compound is also known as oxalic acid in its bis-hydrogenated form.

Dihydroxybutanedioic has a highly polarized molecule, with the two carboxylic acid groups positioned on either side of the butenedioate bridge. The hydroxyl groups are positioned ortho- to the carboxylic acid groups, further enhancing the molecule's polarity.

At standard temperature and pressure conditions, dihydroxybutanedioic exists as a crystalline solid with a melting point of around 161-163 degrees Celsius. It exhibits poor water solubility, making it challenging to prepare aqueous solutions. Dissolved in hot water or organic solvents like ethanol, dihydroxybutanedioic can form colorless solutions.

The structural similarity between dihydroxybutanedioic and other carboxylic acids allows it to exhibit analogous properties, including reactivity in nucleophilic substitution reactions. Notably, the presence of two freely rotatable hydroxyl groups restricts certain conformational isomers, contributing to its functional and chemical properties.

Research on dihydroxybutanedioic is continued owing to its translatability to the biological properties of oxalic acid, a compound estimated to be at relatively high concentration in plants. The bis-hydrogenated form of oxalic acid becomes clearer in upstream chloroplast transpial reaction inhibitors where hydrophobic substitution for carboxyl resites also dis/protection of atoms's important.
