Piperonyldimethyl ether (CAS 51-03-6) is a highly effective and low-toxicity insecticidal enhancer. It enhances the efficacy of insecticides by inhibiting the metabolic enzymes of insects. It is widely used in agricultural and household pest control. It has relatively high safety, but proper operation is required to avoid irritation and environmental risks.
Insecticidal enhancer
Core function: It has no insecticidal activity on its own, but can significantly enhance the efficacy of pyrethroids, rotenone, and carbamate insecticides.
Enhancement principle: It inhibits the cytochrome P450 enzyme in insects' bodies, delays the metabolism of insecticides, and increases their toxicity.
Application scenarios:
Prevention of pests in grain storage (such as rice, wheat, and beans), with a residual effect period of 1-10 months.
Household insecticides (for mosquito and fly control), often combined with pyrethrin (the ratio is usually 10:1).
Enhancement data
The mortality rate of houseflies when using pyrethrin alone is 46%, while when combined with this product (30mg pyrethrin + 400mg caproic dimethyl ether), the mortality rate can reach 92%
Toxicity level
Acute oral LD₅₀ (rat): 11,500 mg/kg (low toxicity)
Acute dermal LD₅₀ (rabbit): 1,880 mg/kg
No carcinogenic reports, but it is irritating to the skin and eyes.
Environmental and operational risks
Environmental hazard: There is a risk of water pollution, and leakage must be prevented.
Flammability and explosiveness: Flammable, with a high flash point (171℃), but it may react with open flames or oxidants upon contact.
Protective measures: During operation, wear a gas mask and rubber gloves, and ensure good ventilation.
