Overview
Bifenthrin is a synthetic pyrethroid insecticide known for its effectiveness against a wide range of pests. It was first developed in the 1980s and has since become a staple in agricultural and household pest control. Its chemical structure mimics natural pyrethrins, offering enhanced stability and potency. Bifenthrin is particularly valued for its long residual activity and low mammalian toxicity, making it a preferred choice for integrated pest management (IPM) programs. It is commonly used in crops like cotton, corn, and fruits, as well as for termite and mosquito control.
Physical and Chemical Properties
Bifenthrin is a crystalline solid with a molecular weight of 422.87 g/mol. It is insoluble in water but dissolves readily in organic solvents such as acetone and methanol. The compound is stable under normal storage conditions but degrades under strong alkaline or acidic conditions. One of its standout features is its photostability, which allows it to remain effective even when exposed to sunlight. This property makes it suitable for outdoor applications. Its low volatility reduces the risk of inhalation exposure, though proper handling is still essential.
Main Applications
In agriculture, bifenthrin is used to control pests like aphids, beetles, and mites. It is applied as a foliar spray or soil treatment, depending on the target pest. The insecticide is also effective against termites, often used in pre-construction treatments to protect buildings. Beyond agriculture, bifenthrin is found in household pest control products, including sprays and granules. Its broad-spectrum activity makes it a versatile tool for pest management professionals. However, its use is regulated in many countries due to its environmental impact, particularly on aquatic ecosystems.
Safety and Storage
Bifenthrin is classified as a moderate hazard by the WHO, with potential risks to aquatic life and non-target insects like bees. Proper PPE, including gloves and masks, is recommended during handling. Storage should be in a cool, dry place, away from food and feed. Spills should be contained and cleaned up immediately to prevent environmental contamination. Disposal must comply with local regulations, as improper disposal can lead to water pollution. Always refer to the material safety data sheet (MSDS) for detailed safety instructions.
B2B Procurement Guide
When procuring bifenthrin, buyers should prioritize suppliers with certifications like ISO or GMP. Verify the product's purity, typically ranging from 95% to 99%, depending on the application. Bulk purchases often attract discounts, but storage capacity must be considered. Regulatory compliance is critical; ensure the product meets local and international standards, such as EPA or EU regulations. Request samples for quality testing before large-scale orders. Establish long-term contracts with reliable suppliers to ensure consistent quality and pricing.
