Description

lambda-Cyhalothrin (CAS No. 91465-08-6) is a highly potent synthetic pyrethroid insecticide widely used in agricultural and public health applications. Its molecular formula, C₂₃H₁₉ClF₃NO₃, reflects its complex structure, featuring a cyclopropanecarboxylate core with chloro-trifluoropropenyl and cyano-phenoxybenzyl substituents. This compound exhibits exceptional insecticidal activity by disrupting sodium channel function in the nervous system of target pests, leading to rapid paralysis and death.

Available in various formulations including emulsifiable concentrates and wettable powders, lambda-Cyhalothrin is valued for its broad-spectrum efficacy against lepidopteran, coleopteran, and dipteran pests while demonstrating low mammalian toxicity when used as directed. The technical material meets stringent purity standards (>95%) with HPLC-UV validation, ensuring consistency for research and commercial applications.

Packaging options range from 100mg analytical standards to 25kg technical grade drums, all supplied with comprehensive certificates of analysis. Storage recommendations include protection from light at 2-8°C in original containers.
