| | NORFLURAZON Usage And Synthesis |
| Chemical Properties | White to gray-brown crystalline solid or powder.
Odorless. | | Uses | Pesticide. | | Uses | Food additive; herbicide. | | Definition | ChEBI: Norflurazon is a pyridazinone that is pyridazin-3(2H)-one which is substituted at positions 2, 4, and 5 by m-(trifluoromethyl)phenyl, chloro, and methylamino groups, respectively. A pre-emergence herbicide used to control grasses and broad-leafed weeds in a variety of crops. Not approved for use within the European Union. It has a role as a carotenoid biosynthesis inhibitor, a herbicide and an agrochemical. It is a pyridazinone, a member of (trifluoromethyl)benzenes, an organochlorine compound and a secondary amino compound. | | General Description | Colorless odorless crystals. Non corrosive. Used as an herbicide. | | Reactivity Profile | A trifluoromethyl pyridazinone derivative. | | Agricultural Uses | Herbicide: Norflurazon is a selective preemergent herbicide
used to control germinating annual grasses, sedges, rushes
and broadleaf weeds in fruits (cranberries, citrus, cherries,
nectarines, apricots), grape vines, vegetables, nuts, cotton,
peanuts, soybeans, and various nonagricultural and industrial
areas. Forbidden for use in the EU after 7/25/2003.
Registered for use in the U.S. Manufactured in the US by
Clariant Corporation, North Carolina. | | Trade name | EVITAL®; H 9789®; SAN 9789 H®;
SAN 97895®; SOLICAM®; TELOK®[C];
TRIETHANOLAMINE DBS®; ZORIAL® | | Safety Profile | When heated to
decomposition emits toxic fumes of NOx,
F-, and Cl-. | | Potential Exposure | Norflurazon is a pyridazinone selective
pre-emergent herbicide used to control germinating
annual grasses, sedges, rushes and broadleaf weeds in fruits
(cranberries, citrus, cherries, nectarines, apricots), grape
vines, vegetables, nuts, cotton, peanuts, soybeans, and various
nonagricultural and industrial areas. Forbidden for use
in the EU after 7/25/2003. Manufactured in the United
States by Clariant Corporation, North Carolina. | | Shipping | UN3077 Environmentally hazardous substances,
solid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous
material, Technical Name Required. | | Incompatibilities | rapidly degraded by strong light; UV.
Incompatible with oxidizers, chlorates nitrates, peroxides. | | Waste Disposal | It is the responsibility of
chemical waste generators to determine the toxicity and
physical properties and of a discarded chemical and to
properly identify its classification and certification as a
hazardous waste and to determine the disposal method.
United States Environmental Protection Agency guidelines
for the classification determination are listed in 40 CFR
Parts 261.3. Additionally, waste generators must consult
and follow all regional, national, state and local hazardous
waste laws to ensure complete and accurate classification
and disposal methods. Follow recommendations for the
disposal of pesticides and pesticide containers. Containers
must be disposed of properly by following package label
directions or by contacting your local or federal environmental
control agency, or by contacting your regional
EPA office. |
