Abstract: The present disclosure relates to crystallizing a chemical substance(s) using ultrasound. Methods are provided for screening a chemical substance according to its solid forms by using ultrasound to generate new or unusual solid forms. Methods are also provided for crystallizing a chemical substance by novel techniques that include sonication. The present disclosure also relates to cocrystallization using ultrasound. Methods are provided for preparing cocrystals of an active agent and a guest by sonicating and crystallizing. Methods are also provided for screening a sample according to solid state phases (such as cocrystals and salts) and include generating a cocrystal from the sample using ultrasound.

Abstract: The present disclosure relates to novel cocrystals and novel methods for cocrystallization. In particular, the disclosure includes cocrystals comprising a salt of an active agent, such as a chloride salt of an active pharmaceutical ingredient. The present disclosure also relates to methods of preparing cocrystals and methods for screening for solid state phases.

Abstract: A method for generating and isolating a high free energy form of a compound or a mixture of compounds comprises the steps of placing a sample in a capillary tube, solidifying the sample in the capillary tube, and isolating a high free energy form of the sample. A method for searching for a high free energy form of a sample comprises the steps of placing the compound or mixture in a capillary tube, generating a solid in the capillary tube, and determining whether a high free energy form of the sample was generated. The sample may be a compound or mixture.

Abstract: Methods for searching for possible forms of a sample and methods of screening a sample according to its form comprise disposing the sample in at least one receptacle that defines a capillary space, such as a capillary tube. The sample is solidified to generate at least one solid form or semisolid form, and the generated form is analyzed and classified. The analysis may determine differences in molecular arrangement of the various forms or characteristics that reflect the form. The methods may employ a plurality of samples, conditions, or receptacles in an effort to generate a variety of forms, so that all or a high percentage of possible forms are obtained.
