Solubility, polymorphism, crystallinity, and crystal habit of acetaminophen and racemic (±)-ibuprofen were determined by initial screening of 23 solvents for scale-up. Solubility curves were constructed, and solubility at 25 °C was plotted against the dielectric constants of various solvent as a fingerprint for solute identification. The total "form space" for acetaminophen and racemic (±)-ibuprofen were calculated to be 222 and 257, respectively. Various crystal habits and sizes for ibuprofen and acetaminophen were observed.
