In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanol, published in 2012-02-29, which mentions a compound: 86404-63-9, Name is 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone, Molecular C10H7F2N3O, Application of 86404-63-9.
In 1-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanol, C10H9F2N3O, the dihedral angle between the rings is 22.90(4)°. In the crystal, C-H···F and O-H···N H bonds link the mols. into chains along [010]. Crystallog. data are given.
Compounds in my other articles are similar to this one(1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone)Application of 86404-63-9, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
