Imidacloprid is a widely used neonicotinoid insecticide recognized for its high efficacy against a broad spectrum of insect pests. As a systemic insecticide , it is absorbed by plants and distributed throughout their tissues, providing comprehensive and long-lasting protection against insect infestations.

Due to its strong insecticidal activity, versatility, and ease of formulation, Imidacloprid API has become a key raw material in agricultural, horticultural, turf, ornamental, and veterinary pest-control products worldwide.

Chemical & Physical Properties

• Molecular Formula: C₉H₁₀ClN₅O₂
• Molar Mass: 255.66 g/mol
• Density: 1.54 g/cm³
• Melting Point: 144 °C
• Water Solubility: 0.061 g/100 mL at 20 °C
• Appearance: Colorless crystalline solid

• Storage Condition: 0–6 °C, protected from heat and light

Mechanism of Action

Imidacloprid acts on the nicotinic acetylcholine receptors (nAChRs) in the insect nervous system. By disrupting nerve signal transmission, it causes paralysis and death of target pests. Its selectivity toward insect receptors ensures high insecticidal efficiency with comparatively low toxicity to mammals when used as directed.

Applications

Agricultural Pest Control

Imidacloprid is highly effective against sucking and biting insect pests, including:

Commonly used on crops such as cotton, cereals, vegetables, fruits, and citrus , helping improve crop yield and quality.

Horticulture and Ornamental Plants

In horticulture, Imidacloprid provides reliable protection for:

Its systemic action ensures long-lasting pest control and reduces the frequency of applications.

Veterinary and Pet Care

In veterinary medicine, Imidacloprid is a key active ingredient in flea control products for dogs and cats. It delivers rapid knockdown of fleas and long-lasting protection, contributing to improved pet comfort and hygiene.

Key Advantages

Environmental and Safety Considerations

Imidacloprid has a relatively short environmental half-life compared to older insecticides and is not highly persistent when applied correctly. Responsible use and adherence to regulatory guidelines are essential to minimize potential risks to non-target organisms and ecosystems.

Packaging & Delivery

Flexible logistics options are available to meet customer needs:

Packaging can be tailored to API supply and formulation requirements.

Conclusion

API Imidacloprid (CAS No.: 138261-41-3) is a proven and versatile neonicotinoid insecticide that plays a critical role in modern pest management. Its systemic action, broad-spectrum effectiveness, and adaptability across agricultural, horticultural, and veterinary applications make it a cornerstone raw material for insect control products worldwide. When used responsibly, Imidacloprid supports higher productivity, healthier crops, and improved animal care.
