Sulfamerazine: Understanding the influence of slip planes in the polymorphic phase transformation through X-ray crystallographic studies and ab initio lattice dynamics
(American Chemical Society, 2015-08-28)
Understanding the polymorphism exhibited by organic active-pharmaceutical ingredients (APIs), in particular the relationships between crystal structure and the thermodynamics of polymorph stability, is vital for the ...
Effects of ball-milling and cryomilling on sulfamerazine polymorphs: A quantitative study
(Elsevier, 2014-04-11)
The effects of ball-milling and cryomilling on sulfamerazine forms I and II (SMZ FI, FII) were investigated using X-ray powder diffraction, infrared and near-infrared (NIR) spectroscopy. Cryomilling resulted in a complete ...
