CAS 165252-70-0 corresponds to Dinotefuran, a third-generation neonicotinoid insecticide developed by Mitsui Chemicals in Japan. It is characterized by containing tetrahydrofuran ring and no halogen, and has strong systemic, rapid acting, and broad-spectrum activity.

Core physical and chemical properties
-Chinese name: Fipronil (also known as Nicotine Furan or Dinotefuran)
-Molecular formula: C ₇ H ₁ N ₄ O ∝; Molecular weight: 202.21
-Structural features: 1-methyl-2-nitro-3- (tetrahydro-3-furanomethyl) guanidine; Replace traditional chloropyridine/thiazole groups with tetrahydrofuran groups
-Appearance: White to light yellow crystalline powder; Melting point: approximately 94.5-107.5 ℃
-Solubility: Excellent water solubility (different from other neonicotinoids), low lipid solubility; logP≈0.68

Mechanism of Action and Application
-Mechanism: Acting on insect nicotinic acetylcholine receptors (nAChR), resulting in nerve conduction blockade
-Characteristics: Strong contact killing, gastric toxicity, and root systemic absorption; Valid for 4-8 weeks; Low dose high activity; Adversarial strains are effective
-Control targets: Aphids, planthoppers, leafhoppers, whiteflies, thrips and other piercing sucking pests; Treat some Coleoptera, Lepidoptera, and hygiene pests (cockroaches, termites) simultaneously
-Applicable crops: rice, wheat, vegetables, fruit trees, cotton, tobacco leaves, etc
-Safety: Relatively low toxicity to mammals, but high toxicity to bees (avoid use during flowering period)

Precautions
-Storage should be sealed, away from light, cool and dry; Belonging to pesticide raw materials/scientific research reagents, non-medical use
-The specific purity specifications (97% -99%+) and packaging vary depending on the purpose (industrial formulation or scientific research standard)
