Waxy solid. Melting point 59-60 ℃, low volatility. Industrial products have a slight fatty ester odor and are almost insoluble in water. It is stable in storage, does not react with most other pesticides, is slightly corrosive, and is easily hydrolyzed by dilute alkali.
Ioxynil octanoate is used for post-emergence control of annual broadleaf weeds, suitable for cereal crops, sugar beets and onions, etc.
ChEBI: Ioxynil octanoate is a benzoate ester and a member of phenols.
Ioxynil-octanoate is commercially synthesised by esterifying ioxynil with octanoic acid. The production process begins with the preparation of the ioxynil intermediate, which involves iodination of 4-hydroxybenzonitrile to introduce the diiodo substituents. This compound is then reacted with octanoic acid or its acid chloride in the presence of a catalyst, typically a base or acid catalyst, to form the octanoate ester. The esterification is conducted under controlled temperature and solvent conditions to ensure high yield and purity.
Selective, systemic with contact action. Photosynthetic electron transport inhibitor at the photosystem II.
