The solution behavior of a model compound, tetrolic acid (TTA), is studied via molecular dynamics simulations in four organic solvents. The results suggest that strong interactions between TTA and solvent molecules (ethanol or dioxane) prevent the formation of carboxylic acid

The application of FTIR spectroscopy to concentrated solutions of tetrolic acid shows, for the first time, a direct relationship between molecular self association in solution and H-bonded motifs in the subsequently crystallised solid phases.
