摘要:
Crystalline forms A and B of 5-methyl-pyridine-2-sulfonic acid [6-methoxy-5-(2-methoxy-phenoxy)-2-pyridin-4-yl-pyrimidin-4-yl]-amide of formula (I) are described, whereby form B is the most stable form. 5-methyl-pyridine-2-sulfonic acid [6-methoxy-5-(2-methoxy-phenoxy)-2-pyridin-4-yl-pyrimidin-4-yl]-amide also forms solvates with, for example, ethanol, acetone, tetrahydrofuran, methanol, isopropanol, 2-butanone and dichloromethane.
摘要:
A device includes a support (1) and at least two seals (2), which are arranged in a row and are hermetically fitted into cavities, and protrude from the support laterally with respect to inlet and outlet openings, one end of the support being provided with an inlet opening (3) and one end being provided with an outlet opening (4), and the seals being provided with a least one inlet opening and one outlet opening, and the support containing at least one first channel (5) which starts at the inlet opening (3) and is continuous, and is arranged in such a way that it opens into the inlet openings in the side walls of the seals arranged in a row, and one second channel (6) which starts at the outlet opening and is continuous, and is arranged in such a way that it opens into the outlet openings in the side walls of the seals arranged in a row. The system is suitable for simultaneous multiple studies, in particular with the use of microtitration plates, and physical measurements of the results directly in the containers, for example of a microtitration plate. The multiple studies may be used to perform screening processes to discover and develop polymorphic and pseudorpolymorphic forms, new formulations and suitable crystallisation conditions.
摘要:
A process for the detection of polymorphic or pseudopolymorphic forms of solid, molecular and crystallizing compounds, or of molecular, cocrystalline compounds or of solid solutions which consist of at least two solid, molecular and crystallizing compounds, in a series investigation using an apparatus for parallel investigations in vessels of an array under different conditions in each vessel, in which substantially only the amorphous form of the crystallizing compound, a solvate of the crystallizing compound or substantially only the amorphous form or a solvate of a compound in a mixture of at least two compounds is used as a suspension or solution, the solutions of amorphous compound having, at the same temperature, a higher content of crystallizable compounds than is achievable with a corresponding crystalline compound.
