Bentazon is a colorless to white crystalline
powder.
ChEBI: Bentazone-sodium is an organic molecular entity.
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.
Selective action, absorbed by foliage with very little translocation. Inhibits photosynthesis (photosystem II).
A potential danger to those involved
in the manufacture, formulation or application of this selective
postemergent thiadiazine herbicide.
