Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials. SDS of cas: 402-49-3, 402-49-3, Name is 1-(Bromomethyl)-4-(trifluoromethyl)benzene, SMILES is FC(C1=CC=C(CBr)C=C1)(F)F, in an article , author is Lamera, Esma, once mentioned of 402-49-3.
The title compound, C21H16N2O3, consists of an indazolone moiety, bearing a phenyl group, fused to a phthalazine ring system (r. m. s. deviation = 0.018 angstrom). The phenyl ring is almost normal to the mean plane of the five-membered ring of the indazolone moiety, making a dihedral angle of 89.64 (7)degrees. The six-membered ring of the indazolone moiety has an envelope conformation, with the central methylene C atom as the flap. In the crystal, molecules are linked via C-H center dot center dot center dot O hydrogen bonds, forming slabs parallel to the bc plane. The slabs are linked via C-H center dot center dot center dot pi and pi-pi interactions [the shortest intercentroid distance involving rings of pyrazolophthalazine moieties is 3.6430 (8) angstrom], forming a three-dimensional structure.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 402-49-3, you can contact me at any time and look forward to more communication. SDS of cas: 402-49-3.
