Processes leading to enantiomerically pure compounds are of utmost importance, in particular for the pharmaceutical industry. Starting from a racemic mixture, crystallization-induced diastereomeric transformation allows in theory for 100 percent transformation of the desired enantiomer. However, this method has the inherent limiting requirement for the organic compound to form a salt. Herein, this limitation is lifted by introducing cocrystallization in the context of thermodynamic deracemization, with the process applied to a model chiral fungicide. We report a new general single thermodynamic deracemization process based on cocrystallization for the deracemization of (R,S)-4,4-dimethyl-1-(4-fluorophenyl)-2-(1H-1,2,4-triazol-1-yl)pentan-3-one. This study demonstrates the feasibility of this novel approach and paves the way to further development of such processes.

Paragraph 0026; 0032; 0033; 0034; 0035, (2017/08/29)
The invention discloses a hapten and its preparation method and application, in particular to a multiple paclobutrazol haptens. The invention also discloses a plurality of paclobutrazol semi-antigen preparation method and its application. The present invention provides the paclobutrazol semi-antigen not only retains the maximum extent of multi-chemical structure, but also by chemical synthetic transformation introduce protein can be coupled with - COOH, the synthetic method is simple, purity, high yield; for this half-antigen as the raw material, preparation for animal immune antigen system immune animal, the resulting antibody titer, specificity, affinity are better; the resulting antibody can be used in enzyme-linked immunoassay kit, easy to use, and the cost is low, detection method efficient, accurate, fast, can simultaneously detect the mass of the sample, is suitable for the soil and the fruit in the food residue of multi-site monitoring and the screening of a large number of samples. The invention the paclobutrazol semi-antigen of multi-play an important role in the detection of. (by machine translation)
