The present invention provides an improved method for preparing, purifying, precipitating, etc., a subject compound for use in a subsequent reaction carried out in suspension. The present invention relies on a precipitating solvent being added to an aqueous solution comprising the subject compound to form a precipitate of the subject compound, which may be further dried and/or purified. Compositions made according to present methods have improved characteristics and properties, such as increased surface and/or reduced density, resulting in a higher reactivity in a subsequent reaction carried out in suspension.
