trans-Permethrin(CAT: R032261) is a synthetic pyrethroid insecticide composed predominantly of the trans-isomer configuration, known for its potent neurotoxic effects on insects. It acts by disrupting voltage-gated sodium channels in nerve cells, causing prolonged depolarization, paralysis, and eventual death. Widely used in agricultural, residential, and public health applications, trans-Permethrin is effective against a broad spectrum of pests including mosquitoes, lice, fleas, and agricultural insects. Compared to its cis-isomer counterpart, the trans form generally exhibits higher photostability and environmental persistence. trans-Permethrin is also utilized in veterinary medicine and textile treatment, supporting integrated pest management strategies while maintaining low mammalian toxicity at regulated doses.
