Bupropion hydrohalide salts yield ten different crystal phases of bupropion (four hydrochloride, two hydrobromide, and four hydroiodide salts). Of these forms, only four have been previously character
A family of organic compounds exhibits an order-disorder transition of its t-butyl group that can be monitored by TR-SHG (Temperature Resolved Second Harmonic Generation). Solid...
An unusual pharmaceutical solid containing a pleuromutilin derivative, succinic acid and water is studied with a combination of physiochemical methods. The parent pleuromutilin derivative creates a ho
The crystallization of nifedipine was studied by means of synchrotron-X-ray diffraction, single-crystal X-ray structural analysis, and Raman spectroscopy. The results of slow evaporation (24 h in mini
Evaluation of phase transitions in a series of hydrogen sulfates (Rb3H(SO4)2, (NH4)3H(SO4)2, K3 H(SO4)2, and Na3H(SO4)2) based on the single-crystal structure analysis has revealed the exact nature of
