- Core Advantages
High-efficiency contact & stomach toxic phenylpyrazole pesticide with unique GABA chloride channel blocking mechanism. It shows outstanding insecticidal activity against pyrethroid, organophosphate resistant pests, low application dosage, long residual effect. Selective toxicity to insects, widely applied in crop pest control, pet flea/tick removal, termite & household insect elimination, grain storage protection. Stable under normal storage conditions, compatible with most pesticide formulations.
2. Physical & Chemical Properties
2.1 Physical Index
- Appearance: White fine crystalline powder
- Odor: Odorless
- Solubility: Slightly soluble in water (1.9–3 mg/L, 20℃); freely soluble in acetone, dichloromethane, DMSO, ethyl acetate; slightly soluble in ethanol; insoluble in alkane solvents
- Melting Point: 200–201 °C
- Boiling Point: Decomposes above 220 °C without full boiling
- Density (20℃): 1.477–1.626 g/cm3
- Vapor Pressure: 3.7×10?? Pa (25℃), extremely low volatility
- Log Pow: 3.5–4.0
- Hygroscopy: Non-hygroscopic
- pH (aqueous suspension): Neutral
2.2 Chemical Properties
- Molecular structure: Pyrazole heterocycle with amino, cyano, sulfinyl trifluoromethyl and dichloro-trifluoromethyl phenyl substituents
- Insecticidal mechanism: Blocks insect GABA-gated chloride ion channels, disrupts nerve signal transmission, causes paralysis and death; weak binding to mammalian GABA receptors for relatively selective toxicity
- Redox reactivity: Sulfinyl group converts to sulfide or sulfone under light/oxidation conditions to form active metabolites
- Photostability: Gradually degraded under strong UV irradiation; light-proof storage required
- Thermal Stability: Stable below 180℃; thermal decomposition releases fluoride, cyanide and sulfur-containing fragments over melting point
- Acid & Alkali Stability: Stable in pH 5–9 neutral/weak acid-base environment; accelerated hydrolysis under strong acid or strong alkali heating
- Compatibility: Compatible with emulsifiers, most agrochemical solvent carriers; incompatible with strong oxidants, concentrated mineral acids
3. Main Application Fields
3.1 Agricultural Crop Pest Control (Core Usage)
- Foliar spray: Controls rice planthoppers, stem borers, diamondback moths, thrips, cotton boll weevils, potato beetles;
- Soil & seed treatment: Eliminates corn rootworms, wireworms, underground grubs, locusts; effective against pesticide-resistant pest populations.
3.2 Veterinary Pet Parasite Control
Topical spot-on, spray and shampoo raw material for dogs & cats; kills fleas, ticks, lice and mites, long-lasting anti-parasite effect.
3.3 Public Health & Urban Pest Management
Termite barrier treatment, cockroach/ant gel bait, household insect aerosol raw material; controls structural pests and sanitary insects.
3.4 Grain Storage & Turf Protection
Prevents stored grain beetle infestation; granular turf pesticide for lawn mole crickets, grubs and surface pests.
3.5 Biochemical Research Reagent
Laboratory GABA receptor antagonist standard for neurobiology and pesticide mechanism research.
