1 Comparison with Solvent-based Co-crystallisation Techniques [Pg.157]

2 Screening for Co-crystals Using Neat and Liquid-assisted Grinding [Pg.159]

An attractive aspect of co-crystallisation in the synthesis of new API forms is the possibility of forming co-crystals containing identical constituents in different stoichiometric ratios.Mechanochemical methods provide a particularly simple procedure for constructing such stoichiometric variations by simply grinding different amounts of starting materials. This was first demonstrated for the model API caffeine upon co-crystallisation with acetic [Pg.162]

The synthesis of stoichiometric variations was systematically investigated for co-crystals of the model API nicotinamide with various dicarboxylic acids. [Pg.163]
