Description

D-trans-Allethrin is a synthetic pyrethroid insecticide known for its high insecticidal activity and low mammalian toxicity. This compound is a key active ingredient in a wide range of pest control formulations, valued for its rapid knockdown effect against flying and crawling insects. It is essential for manufacturers in the public health, household, and agricultural sectors seeking effective and reliable insecticide solutions.

Application

• Public Health Insecticides: A primary active ingredient in mosquito coils, electric vaporizer mats, and aerosol sprays for indoor and outdoor use.
• Household Pest Control: Formulated in sprays, foggers, and powders for controlling flies, cockroaches, ants, and other domestic pests.
• Agricultural Applications: Used in certain crop protection products to manage insect pests, often in combination with other active ingredients.
• Animal Health: Incorporated into pet care products such as shampoos, sprays, and collars for flea and tick control.
• Industrial & Institutional (I&I): Used in pest management programs for food processing plants, warehouses, and commercial facilities.
• Textile Treatment: Applied for moth-proofing wool and other fabrics.

Quality Control

Our D-trans-Allethrin is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC, GC, and IR spectroscopy, to meet the specifications required for insecticide formulation. A Certificate of Analysis (COA) detailing purity, isomer content, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere such as nitrogen. Keep away from heat, sparks, and open flame.
