The Use of Co-crystals for the Determination of Absolute Stereochemistry: An Alternative to Salt Formation Kevin S. Eccles Rebecca E. Deasy László Fábián Anita R. Maguire Simon E.

Co-crystallization involves generating a crystalline material consisting of more than one neutral compound. The combination of co-crystallization with both X-ray diffraction and chiral HPLC was particularly powerful in overcoming these difficulties for a series of chiral 3-arylbutanoic acids. Co-crystallization offers advantages over salt formation because co-crystals dissociate in solution, meaning identical HPLC conditions can be used for both the materials of interest and their co-crystals. 2011-02-18 00:00:00 series acid Salt FormationAbsolute stereochemistry HPLC conditions chiral HPLC Determination salt formation arylbutanoic combination material solution difficulty meaning compound diffraction Absolute Stereochemistry Alternative
