| Hazard Information | Back Directory | [Uses]
Rabenzazol is a pyrazole fungicide used to treat plants and vegetables. Pesticide component. | [Production Methods]
Rabenzazole is prepared through a three‑step heterocyclic construction sequence: first, treatment of a benzimidazole precursor with hydrazine hydrate under reflux, followed by a second reflux step in isopropyl alcohol, and finally a diazotization/oxidative cyclisation step using acetic acid and sodium nitrite under ice‑cooled conditions. | [Mechanism of action]
Inhibits the synthesis of β-tubulin during mitosis of fungi | [Pesticide Type]
