Currently to obtain polymorphic forms of drugs various methods are used including single and multi-solvent crystallization, lyophilization, sublimation, spray drying, sublimation, grinding, etc. [11,18].Polymorph properties should include the morphology of crystals, their crystallographic parameters, … WebApr 13, 2024 · ABSTRACT. Crystal nucleation rates have been measured in the supercooled melts of two richly polymorphic glass-forming liquids: ROY and nifedipine (NIF). ROY or 5-methyl-2- [ (2-nitrophenyl)amino]-3-thiophenecarbonitrile is known for its crystals of red, orange, and yellow colors and many polymorphs of solved structures (12).

WebIt was once thought that cocrystals could be a means to prevent polymorphism but many recent examples of cocrystal polymorphism have been discovered and reported. Similar to single component crystals, polymorphs of cocrystals can display significantly different properties. In this contribution, we present a survey of polymorphic cocrystals. ...
