The structure of the title compound, C(19)H(20)N(2)O(2)S, displays inter-molecular N-H⋯O hydrogen bonding, which generates inversion dimers. There is no π-π stacking in the crystal structure. The dihedral angle between the phenyl ring and naphthalene ring system is 59.16 (11)°.

The title compound, C(15)H(21)N(3)O(3)S, is known to be an impurity of gliclazide [systematic name: N-(hexa-hydro-1H-cyclopenta[c]pyrrol-2-ylcarbamo-yl)-4-methyl-benzene-sulfonamide], a sul-fonyl-urea anti-diabetic drug. Gliclazide has a p-tolyl group substituting the sulfonamide functionality, while the title mol-ecule contains an o-tolyl group. Both five-membered fused rings adopt envelope co...

Four phenylalanine nitrogen mustards were tested against the S91 Cloudman mela noma in young male mice. Two of the mustards carried the di (2-chloroethyl) amino group in the meta position but differed in respect to the location of the amino group in the alanine side chain. Likewise, two of the mustards carried the di(2-chloroethyl)amino group in the para position, again differing, however, in l...

In the title compound, C(21)H(23)NO(4)S, the dihedral angle between the naphthalene residue and the benzene ring is 7.66 (3)°. In the molecule, there are some short C-H⋯O interactions. In the crystal, the structure is stabilized by weak intra-molecular C-H⋯O hydrogen bonds and the crystal structure is stabilized by weak C-H⋯O, C-H⋯π and π-π [centroid-centroid distance = 3.710 (2) Å] inter-actions.

The crystal structure of the title compound, [Ru(C(10)H(15))(C(7)H(9)NO(2)S)]C(24)H(20)B, has been determined as part of our investigation into the structural and biological properties of organometallic Ru(II)-arene-Cp* complex salts of the type [R-PhRuCp*](+)·X(-) (where Cp* is penta-methyl-cyclo-penta-diene). Tethering the RuCp* group to the benzene ring of p-toluene-sulfonamide results in on...

In this investigation, the influence of doping graphene with silicon in the adsorption of alanine amino acid was inspected computationally. For this purpose, the structures of pure graphene, silicon doped graphene, alanine and 10 derived products of the alanine reaction with pure and silicon doped nano-adsorbents were optimized geometrically. Afterwards, the values of adsorption energy, formati...

Styrene is widely used as one of the most important industrial materials for the production of synthetic rubbers, plastic, insulation, fiberglass, and automobile parts. Inhaled styrene has been reported to produce respiratory toxicity in humans and animals. Styrene oxide, a reactive metabolite of styrene formed via cytochrome P450 enzymes, has been reported to form covalent bonds with proteins,...

In the title compound, C(20)H(17)BrClNO(2)S, the dihedral angle between the benzene ring and the naphthalene plane is 8.95 (8)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O, C-H⋯Cl and π-π [centroid-centroid distance = 3.8782 (16) Å] inter-actions.
