Descriptions:
pubchem: 2-(4-isopropyl-4-methyl-5-oxo-4,5-dihydro-1H-imidazol-2-yl)nicotinic acid is a pyridinemonocarboxylic acid that is nicotinic acid which is substituted at position 2 by a 4,5-dihydro-imidazol-2-yl group, which in turn is substituted at positions 4, 4, and 5 by isopropyl, ethyl, and oxo groups, respectively. It is an imidazolone, a pyridinemonocarboxylic acid, a member of pyridines and a member of imidazolines.
chebi: A pyridinemonocarboxylic acid that is nicotinic acid which is substituted at position 2 by a 4,5-dihydro-imidazol-2-yl group, which in turn is substituted at positions 4, 4, and 5 by isopropyl, ethyl, and oxo groups, respectively.
chembl: IMAZAPYR is a small molecule listed in the ChEMBL database but has not progressed to an approved clinical phase.
wikipedia: Imazapyr is a non-selective herbicide used for the control of a broad range of weeds including terrestrial annual and perennial grasses and broadleaved herbs, woody species, and riparian and emergent aquatic species.
Imazapyr is an ingredient of the commercial product Ortho GroundClear. A related herbicide, imazapic is an ingredient in Roundup Extended Control.  Both chemicals are non-selective, long-lasting, and effective in weed control. Water-soluble, depending on soil type and moisture, they can move into parts of the landscape where they were not sprayed.  Some desirable landscape plants are especially sensitive to them and can be damaged.
Imazapyr's HRAC classification is Group B (global, Aus), Group 2 (numeric), as it inhibits acetohydroxyacid synthase.
