The crystal structure of the title compound, C(11)H(16)N(2)O(2), contains two crystallographically independent mol-ecules forming dimers by pairs of inter-molecular N-H⋯N hydrogen bonds. The two mol-ecules are related by a pseudo-twofold axis. The dihedral angle between the pyridine ring and the carbamate plane differs in the two mol-ecules [12.1 (3) and 3.5 (3)°].

The title salt, C(14)H(31)N(2) (+)·C(15)H(9)O(7) (-), was obtained in the reaction of quercetin with n-butyl-amine in a mixture of acetone and hexane. The crystal structure determination shows that the quercetin donates one of its phenol H atoms to the N-butyl-4-butyl-imino-2-methyl-pentan-2-amine mol-ecule. The crystal structure of the salt is stabilized by intramolecular (N-H⋯N for the cation...

The effects of combined exposure to n-butyl alcohol and n-butyl acetate on rotarod performance and hot plate behaviour in rats and respiratory rate in mice were investigated in the condition of an acute inhalation experiment. Rotarod performance and hot-plate behaviour were tested in rats exposed to various concentrations of n-butyl alcohol, n-butyl acetate and their mixture consisting of 50 Vo...

The title compound, C(20)H(32)N(2)O(2)S, the condensation product of a thio-acetohydrazine and acetone, has a two-coordinate S atom and the angle at this atom is 100.7 (1)°. The (CH(3))C=N-NH-C(O)- substituent engages in N-H⋯O hydrogen-bonding inter-actions with the substituent of an adjacent mol-ecule across a center of inversion, generating a dimeric structure.

In the title compound, C(15)H(19)N(3), the pyrimidine ring is approximately planar [maximum deviation = 0.007 (1) Å] and forms a dihedral angle of 3.15 (6)° with the benzene ring. In the crystal packing, inter-molecular N-H⋯N hydrogen bonds link pairs of neighbouring mol-ecules into dimers with R(2) (2)(8) ring motifs. These dimers are stacked along the b axis.
