Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (2S)-(+)-3-Chloropropane-1,2-diol, is researched, Molecular C3H7ClO2, CAS is 60827-45-4, about Solid Phase Behavior, Polymorphism, and Crystal Structure Features of Chiral Drug Metaxalone.Application of 60827-45-4.
In addition to the previously known A-rac and B-rac polymorphs of the chiral drug metaxalone 1, an enantiopure A-(S)-form was obtained and studied. According to x-ray anal., the crystalline organization of this form is close to the A-rac-1 polymorph. Crystallization of metaxalone melts is accompanied by the formation of a previously unknown metastable C-phase, which in the case of both racemic and enantiomeric samples are transformed into A-rac-1 or A-(S)-1. Anal. of the PXRD and IR spectra of crystalline samples revealed a similarity of the internal structure for the A-(S)-1, A-rac-1, C-(S)-1, and C-rac-1 crystalline forms and the essential difference of all of these phases from the B-rac-1 phase. According to the thermochem. data, the dependences of the change in the Gibbs free energy for all the phases studied are plotted in the interval from the m.p. to 20°. Under standard conditions, the crystalline modifications of metaxalone, relative to ΔG0, form such a series: B-rac-1 < A-(S)-1 ≈ A-rac-1 < C-rac-1 < C-(S)-1. A model that describes all the exptl. revealed features of metaxalone crystallization is proposed. This literature about this compound(60827-45-4)Application of 60827-45-4has given us a lot of inspiration, and I hope that the research on this compound((2S)-(+)-3-Chloropropane-1,2-diol) can be further advanced. Maybe we can get more compounds in a similar way.
