WebN2 - 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. WebRecently, a second crystalline polymorph (Form II) of racemic ibuprofen was reported to be obtained by crystallization from the supercooled liquid state. The reported procedure involved a temperature schedule that included the requirement to quench the sample to a temperature (168 K) significantly below the glass-transition temperature (228 K) followed …
