Impact of Molecular Flexibility on Double Polymorphism, Solid Solutions and Chiral Discrimination during Crystallization of Diprophylline Enantiomers
Clément Brandel,Youness Amharar,Judith M. Rollinger,Ulrich J. Griesser,Yohann Cartigny,Samuel Petit,Gérard Coquerel +6 more
TL;DR: The resolution of DPL enantiomers despite the existence of a racemic compound stable at any temperature demonstrates that the detection of a stable conglomerate is not mandatory for the implementation of preferential crystallization.
Journal ArticleDOI
Thermodynamic description of the Cr–Nb–Si isothermal section at 1473 K
TL;DR: In this paper, an assessment of the ternary Cr-Nb-Si system is presented based on the description proposed by Costa-Neto et al. and Du and Schuster for the Cr−Si system.
Journal ArticleDOI
Naproxen–Nicotinamide Cocrystals: Racemic and Conglomerate Structures Generated by CO2 Antisolvent Crystallization
Clémence Neurohr,Mathieu Marchivie,Sophie Lecomte,Yohann Cartigny,Nicolas Couvrat,Morgane Sanselme,Pascale Subra-Paternault +6 more
TL;DR: In this article, a novel racemic cocrystal structure containing both enantiomers of naproxen linked to nicotinamide has been produced thanks to the CO2 antisolvent batch crystallization process.
Journal ArticleDOI
Structural Aspects of Solid Solutions of Enantiomers.
TL;DR: The aim is to review published cases of enantiomeric solid solutions for which both melting phase diagrams and crystal structures are available in order to analyze the lack of chiral discrimination associated to these phases.
Journal ArticleDOI
Mechanisms of Reversible Phase Transitions in Molecular Crystals: Case of Ciclopirox
Clément Brandel,Yohann Cartigny,Nicolas Couvrat,M. Ermelinda S. Eusébio,João Canotilho,Samuel Petit,Gérard Coquerel +6 more
TL;DR: In this paper, a detailed characterization of several subambient solid state transitions occurring in the pharmaceutical ingredient Ciclopirox between −20 °C and −85 °C was performed by using a combination of DSC, cold-stage optical microscopy, vibrational spectroscopies, solid state NMR at controlled temperature, structural analyses by single crystal X-ray diffraction, and temperature-resolved Xray powder diffraction.
