The goal of this study was to provide a better framework for understanding the bulk and surface disorder in milled crystalline materials. The surface and bulk properties of two model compounds, ketoconazole and griseofulvin, were characterized by inverse gas chromatography as a function of cryomilli

The feasibility of using excipients to suppress the amorphization or structural disorder of crystalline salbutamol sulphate (SS) during milling was investigated. SS was subjected to ball-milling in the presence of a-lactose monohydrate (LAC), adipic acid (AA), magnesium stearate (MgSt), or polyvinyl
The experimental two-component phase diagram between the orientationally disordered crystals 2-amino-2-methyl-1,3-propanediol (AMP) and 1,1,1-tris(hydroxymethyl)propane (PG) has been established from room temperature to the liquid state using thermal analysis and X-ray powder diffraction techniques.
## Abstract **BACKGROUND:** Rβmandelic acid is an important chiral pharmaceutical intermediate, which is commonly obtained by biotransformation. This work has focused on using novel chiral recognition technology, aqueous twoβphase extraction, for the chiral separation of mandelic acid. **RESULTS:*
