Metrafenone

Metrafenone is a fungicide used in pesticide formulations in the protection of vegetation and crops.

ChEBI: A member of the class of benzophenones that is benzophenone in which one of the phenyl groups is substituted by methoxy groups at positions 2, 3, and 4 and by a methyl group at position 6, while the other is substituted at positions 2, 3, and 6 by methyl, romine, and methoxy groups, respectively. A fungicide with protectant and curative properties, it is used for the control of powdery mildew in cereals and grape vines.

Metrafenone is commercially produced through a specialized organic synthesis process tailored for its use as a fungicide. While detailed production steps are proprietary and not widely disclosed, the synthesis typically involves constructing a benzophenone backbone with specific substitutions that confer antifungal activity. The process includes controlled reactions such as acylation and halogenation, followed by purification to achieve high chemical purity—often exceeding 99% for agricultural formulations.

Protective and curative action. Interferes with hyphal morphogenesis.
