5 Synthesis and biological evaluation of a series (N = 16) of cyclic and acyclic hydroxyurea derivatives, including benzotriazole-, isocyanuric acid- and biuret-containing compounds, are disclosed. 1-N-(benzyloxycarbamoyl)benzotriazole was used as a benzyloxyisocyanate donor, a useful intermediate in the preparation of substituted hydroxyurea. Antibacterial activities of synthesized hydroxyurea...

Despite the widespread use of benzotriazoles and benzothiazoles and the occurrence of these compounds in wastewater treatment plants (WWTPs), no earlier study has comprehensively examined their fate in WWTPs. In this study, an integrated liquid chromatography-tandem mass spectrometry (LC–ESI(+)MS/MS) method was developed and validated for simultaneous determination of four benzotriazoles and fo...

In the title compound, C(21)H(18)N(8), the two (benzotriazol-1-yl)methyl groups are located in an anti position with respect to the benzimidazoline moiety. The dihedral angles between the benzotriazole ring systems and the central benzimidazoline moiety are 57.03 (4) and 81.01 (3)°. The crystal packing is stabilized by two C-H⋯π inter-actions.

In the title mol-ecule, C(14)H(13)N(3)O, the dihedral angle between the mean planes of the benzotriazole ring system and the benzene ring is 57.8 (2)°.

In the title compound, C(15)H(12)FN(3)O, the benzotriazole ring system is essentially planar, with a maximum deviation from the least-squares plane of 0.016 (3) Å. The dihedral angle between this ring system and the fluoro-substituted benzene ring is 67.97 (2)°. The crystal structure is stabilized by weak inter-molecular C-H⋯N inter-actions.

Abstract A rapid, sensitive, economically and ecologically friendly method based on one-step ultrasound-assisted emulsification microextraction in situ derivatization followed by gas chromatography–mass spectrometry for simultaneous determination of low molecular benzotriazoles benzotriazole-based ultraviolet filters was developed. The optimized allows quantification benzotriazole, 4-methylbenz...

ABSTRACT The common corrosion inhibitor, 1H-benzotriazole (Bz), found as a component of glycol-based aircraft deicers, and its derivatives such as 5-chloro-1H-benzotriazole (CBz), 1-hydroxy-benzotriazole (HBz), and 5-methyl-1H-benzotriazole (MBz), are all potential nitrification inhibitors. The inhibitory effect on the nitrification of urea-N fertilizer in agricultural soils was examined over a...

Benzotriazole corrosion inhibitors are not completely removed during wastewater treatment and are frequently detected in surface waters. Here, the photochemical kinetics of benzotriazoles and structurally related compounds were assessed for natural aqueous environments. The direct photochemical half-lives during exposure to simulated sunlight ranged from 1.3 to 1.8 days for benzotriazole and it...

The asymmetric unit of the title compound, C6H5N3·C7H6O3, comprises independent benzotriazole and 4-hydroxybenzoic acid molecules. The dihedral angle between the benzene ring and the benzotriazole ring system is 15.18 (7)°. The mean plane of the carb-oxyl group is twisted at an angle of 18.55 (1)° with respect to the benzene ring. The crystal structure is stabilized by weak inter-molecular N-H⋯...

In the title compound, C(7)H(6)ClN(3), the benzotriazole ring is essentially planar with a maximum deviation of 0.0110 (15)Å, and makes a dihedral angle of 0.46 (8)° with the benzene ring. In the crystal, mol-ecules are linked through inter-molecular C-H⋯N hydrogen bonds, forming chains along the c axis.
