The corresponding substance of CAS 66215-27-8 is cyromazine, a 1,3,5-triazine insect growth regulator that specifically inhibits the development of dipteran insect larvae.

Core Basic Information
-Chinese name: Cyclopropane (also known as Imidacloprid, Mecloprid, and Fipronil)
-English name: Cyromazine
-Chemical name: N-Cyclopropyl-1,3,5-triazine-2,4,6-triamine
-Molecular formula: C ₆ H ₁₀ N ₆
-Molecular weight: 166.18
-Appearance: Pure product is a white or light yellow crystalline solid
-Melting point: 219-227 ℃
-Solubility: The solubility in water is about 11000 mg/L (20 ℃, pH 7.5), slightly soluble in methanol/ethanol
-Toxicity level: Low toxicity (acute oral LD ₅₀ ≈ 3387 mg/kg in rats)

Mechanism and characteristics of action
1. Mechanism of action: interferes with the morphological development of Diptera larvae and pupae, hinders molting and pupation processes, leading to incomplete adult emergence or death; It has no direct lethal effect on adult insects, but can reduce the hatching rate of eggs.
2. Transmission characteristics: It has strong internal absorption, and the leaf spray can be transmitted to the whole plant. Soil application can be absorbed by the root system and transported upward.
3. Selectivity: Mainly targeted at Diptera (such as Drosophila melanogaster, maggots, and housefly larvae), it is relatively safe for natural enemies such as insects and mammals.
4. Residual metabolism: After oral administration, animals are rarely absorbed, and about 99% are excreted in their original form with feces, playing a role in killing maggots in feces.

Main application areas
-Agricultural crop protection: prevention and control of pests such as American leafminer, onion and garlic root maggot on crops such as cucumber, chives, garlic, and beans; The dosage forms include suspension agents, wettable powders, soluble powders, etc.
-Animal husbandry and veterinary medicine: mixed feeding or drinking water is used for controlling fly larvae in livestock and poultry houses, blocking the breeding chain by eliminating maggots through feces, and improving the breeding environment.
-Caution for use: Do not mix with alkaline agents; Need to rotate medication to prevent drug resistance; Some studies suggest that its metabolites contain trace amounts of melamine structure, and attention should be paid to food residue limits (such as eggs ≤ 0.3 mg/kg).

Safety and Storage
-Irritation: It has a mild to moderate irritant effect on the eyes and skin, and protective equipment should be worn during operation.
-Storage conditions: Sealed and stored in a cool and dry place, away from oxidants and food and beverages.
-Non hazardous chemicals: not classified as flammable/explosive/highly toxic in the list of hazardous chemicals, but within the scope of pesticide supervision (pesticide registration certificate is required for import and export).
