Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter.17852-52-7, Name is 4-Hydrazinylbenzenesulfonamide hydrochloride, SMILES is O=S(C1=CC=C(NN)C=C1)(N)=O.[H]Cl, belongs to phthalazine compound. In a document, author is Bouraiou, Abdelmalek, introduce the new discover, Quality Control of 4-Hydrazinylbenzenesulfonamide hydrochloride.
In the title compound, C22H18N2O4, the three fused rings of the pyrazolophthalazine moiety are coplanar (r.m.s. deviation = 0.027 angstrom). The cyclohexene ring fused to the pyrazolidine ring, so forming the indazolophthalazine unit, has a half-chair conformation. The benzene ring is almost normal to the mean plane of the pyrazolophthalazine moiety, with a dihedral angle of 87.21 (6)degrees between their planes. In the crystal, molecules are linked by pairs of C-H center dot center dot center dot O hydrogen bonds forming inversion dimers. The dimers are linked via C-H center dot center dot center dot pi interactions, forming slabs parallel to (100). Between the slabs there are weak pi-pi interactions [ shortest inter-centroid distance = 3.6664 (9) angstrom], leading to the formation of a three-dimensional structure.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 17852-52-7 is helpful to your research. Quality Control of 4-Hydrazinylbenzenesulfonamide hydrochloride.
