Chemistry can be defined as the study of matter and the changes it undergoes. 254-60-4. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.254-60-4, Name is 1,8-Diazanaphthalene, molecular formula is C8H6N2, introducing its new discovery.
A new kind of co-crystal of buprofezin (C16H24FN3OS) with hydrofluoric acid has been prepared through evaporation technique. It crystallizes in the triclinic space group P1, with alpha = 9.9733(8), b = 10.3460(9), c = 10.5739(12) A, alpha = 68.655(9), beta = 73.291(9), gamma= 66.738(8), V = 920.34(17) A3, Mr = 325.44, Dc = 1.174 g/cm3, Z = 2, F(000) = 348, mu= 0.190 mm-1, the final GOOF = 1.042, R = 0.0485 and wR = 0.1167. Single-crystal X-ray diffraction, XRPD, DSC, TGA, Hirshfeld surface analysis, Raman spectroscopy and FT-IR were used to characterize the co-crystal. It has a two-dimensional plane structure, and the intermolecular interactions of co-crystal are mainly H-F H, H-O H and H-O H. Thermology study further confirmed that co-crystal has stronger thermal stability and higher melting point than buprofezin, and it has stronger water solubility. The results show that this co-crystal is valuable for the study of residual activity and application effects of buprofezin.
