Benzotriazole ultraviolet stabilizers (BZT-UVs) have previously been found in sludge from wastewater treatment plants (WWTPs), which might be potential sources of BZT-UVs to the surrounding environment. In this work, the occurrence and fate of seven emerging 2-hydroxyphenyl substituted BZT-UVs were investigated in a Chinese WWTP. This group of hydrophobic BZT-UVs possess log Kow values ranging ...

In recent years, the use of antifungal drugs in human medicine has increased, especially with the advent of AIDS epidemic. Efforts have focused on the development of new, less toxic and more efficacious antifungal drugs with novel mechanism of action. The purpose of this study was to synthesize of some new benzimidazole, benzotriazole and aminothiazole derivatives and to evaluate their activity...

The electrical resistance and polarization effect of cement paste containing reinforcement were tested to research the anti-corrosion properties steel bars in paste. Moreover, microstructure composition passivation film rust on studied. water–cement ratio this study was 0.3, with 0.5% NaCl, 1% NaNO2, Benzotriazole, an assembly unit NaNO2 + Benzotriazole by mass added provide a chloride environm...

The idea of smart inhibitors is based on the principle that an inhibitor is used where needed. This will reduce the use of inhibitors and protect materials in hostile environments. On the other hand, direct addition of the inhibitor within the coating can be harmful, resulting in the loss of inhibitors ability, deterioration in the coating or both of them. An appropriate method for solving thes...

In the title compound, C(22)H(15)BrClN(3)O(3), the benzotriazole ring system makes dihedral angles of 2.43 (1) and 71.51 (1)° with the bromo-phenyl and chloro-phenyl rings, respectively; the angle between the latter two rings is 69.26 (1)°. In the crystal structure, mol-ecules are linked into chains by inter-molecular C-H⋯O hydrogen bonds. The crystal packing is further stabilized by π-π (with ...

In the title compound, C(13)H(11)N(3), the benzotriazole ring system is essentially planar, with a maximum deviation of 0.0173 (18) Å, and forms a dihedral angle of 75.08 (8)Å with the phenyl ring. In the crystal, pairs of weak C-H⋯N hydrogen bonds form inversion dimers. In addition, there are weak C-H⋯π(arene) inter-actions and weak π-π stacking inter-actions, with a centroid-centroid distance...

In the title compound, C(14)H(11)N(3)O(2), the dihedral angle between the mean planes of the benzotriazole ring system and the benzene ring of the salicylaldehyde group is 2.4 (2)°. There is an intra-molecular O-H⋯N hydrogen bond which may influence the mol-ecular conformation.

Severe acute respiratory syndrome (SARS) is caused by a newly emerged coronavirus that infected more than 8000 individuals and resulted in more than 800 fatalities in 2003. Currently, there is no effective treatment for this epidemic. SARS-3CL(pro) has been shown to be essential for replication and is thus a target for drug discovery. Here, a class of stable benzotriazole esters was reported as...
