CAS 57960-19-7 corresponds to Acequinocyl, a naphthoquinone based contact killing acaricide that exerts its efficacy by inhibiting mitochondrial electron transport chain complex III. It is widely used for the prevention and control of mites in fruit trees and vegetables.

Basic Information
-Chinese name: Imidacloprid Quinone
-English name: Acequinocyl
-Chemical name: 2- (Acetoxy) -3-Dodecyl-1,4-Naphthoquinone (or (3-Dodecyl-1,4-Dioxo-1,4-dihydronaphthalen-2-yl) Acetate)
-Molecular formula: C ₂₄ H ∝₂ O ₄
-Molecular weight: 384.52
-Appearance: Light yellow powdery solid
-Melting point: 59.6 ℃
-Solubility: Very low solubility in water (~6.69 μ g/L, 20 ℃), easily soluble in organic solvents such as toluene and dichloromethane

Mechanism and characteristics of action
1. Mode of action: mainly contact killing, with feeding toxicity; No intrinsic absorption activity.
2. Mechanism: Hydrolyzed into 2-dodecyl-3-hydroxy-1,4-naphthoquinone in mites, it binds to the Qo site of mitochondrial electron transport chain complex III, blocking electron transfer and leading to energy metabolism failure.
3. Mite killing spectrum: Effective against various herbivorous mites such as red spider mites; Relatively safe for beneficial organisms such as predatory mites and parasitic wasps.
4. Environmental behavior: Degradation in soil is relatively fast (DT ₅₀ 1.7-3.8 days), with a short hydrolysis half-life and difficulty in accumulation.

Application and Security
-Main crops: citrus, pear, peach, grape, cucumber and other fruit trees and vegetables.
-Toxicity level: low toxicity (oral LD ₅₀>5000 mg/kg in rats); Highly acute toxicity to fish and aquatic organisms (GHS09, H410).
-Registration status: Formally registered in China in 2025 (raw material and 15% emulsion formulation) for the prevention and control of citrus red spider mites.
-Storage suggestion: Avoid light, store at low temperatures (0-6 ℃ or -20 ℃ for standard products), and seal against moisture.
