TY - JOUR A1 - Chewle, Surahit A1 - Emmerling, Franziska A1 - Weber, M. T1 - Effect of choice of solvent on crystallization pathway of paracetamol: An experimental and theoretical case study JF - Crystals N2 - The choice of solvents influences crystalline solid formed during the crystallization of active pharmaceutical ingredients (API). The underlying effects are not always well understood because of the complexity of the systems. Theoretical models are often insufficient to describe this phenomenon. In this study, the crystallization behavior of the model drug paracetamol in different solvents was studied based on experimental and molecular dynamics data. The crystallization process was followed in situ using time-resolved Raman spectroscopy. Molecular dynamics with simulated annealing algorithm was used for an atomistic understanding of the underlying processes. The experimental and theoretical data indicate that paracetamol molecules adopt a particular geometry in a given solvent predefining the crystallization of certain polymorphs KW - Crystallization KW - Nucleation KW - Polymorphism KW - Raman spectroscopy KW - Cassical nucleation theory PY - 2021 UR - https://nbn-resolving.org/urn:nbn:de:kobv:b43-520052 DO - https://doi.org/10.3390/cryst10121107 SN - 2073-4352 VL - 10 IS - 12 SP - 1 EP - 10 PB - MDPI CY - Basel AN - OPUS4-52005 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER -
