| Hazard Information | Back Directory | [Chemical Properties]
Bentazon is a colorless to white crystalline
powder. | [Potential Exposure]
A potential danger to those involved
in the manufacture, formulation or application of this selective
postemergent thiadiazine herbicide. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. | [Shipping]
UN2588 Pesticides, solid, toxic, Hazard Class:
6.1; Labels: 6.1—Poisonous materials, Technical Name
Required. | [Incompatibilities]
Keep away from flammable materials,
heat and flame. Risk of fire and explosion if formulations
contain flammable/explosive solvents. | [Waste Disposal]
In accordance with
40CFR165, follow recommendations for the disposal of
pesticides and pesticide containers. Must be disposed properly
by following package label directions or by contacting
your local or federal environmental control agency, or by
contacting your regional EPA office. | [Definition]
ChEBI: Bentazone-sodium is an organic molecular entity. | [Production Methods]
Bentazone-sodium is produced by first manufacturing technical bentazone through the established condensation of o aminobenzenesulfonamide with isopropyl chloroformate to form the benzothiadiazine herbicide core. Once the technical active is obtained, commercial producers convert it into the sodium salt to improve water solubility, and stability. This is done by dissolving or suspending bentazone in water or a mixed solvent and treating it with sodium hydroxide or another sodium base under controlled pH, forming the sodium salt via deprotonation of the sulfonamide moiety. | [Mechanism of action]
Selective action, absorbed by foliage with very little translocation. Inhibits photosynthesis (photosystem II). | [Pesticide Type]
Herbicide |
