    Alpha Cypermethrin CAS 67375-30-8

    Alpha Cypermethrin (CAS 67375-30-8), chemically identified as a high-purity synthetic pyrethroid ester, is a potent technical grade active ingredient employed in agricultural insecticide formulation. This racemic mixture, technically known as alphamethrin or (S)-alpha-cyano-3-phenoxybenzyl (1R)-cis-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate, functions as a broad-spectrum neurotoxin acting by contact and ingestion, and is processed into various end-use forms such as EC, SC, and WP for crop protection and vector control. We provide bulk supply of this technical material with competitive factory pricing to facilitate efficient agrochemical production. Our compliance documentation ensures global trade standards are met, making MSDS, TDS, COA available alongside customized specifications to align with formulation stability requirements.

    Product Description

    Alpha Cypermethrin is an alpha-cyano pyrethroid known for its strong insecticidal activity against a broad spectrum of pests such as flies, mosquitoes, aphids, thrips, whiteflies, beetles, and other chewing and sucking insects. It acts by interfering with sodium channels in the insect nervous system, resulting in paralysis and rapid knockdown.

    It is widely used in crop protection (vegetables, fruits, cotton, corn, rice), animal husbandry, grain storage, and public health pest control. The product shows strong photostability and excellent field persistence, making it an ideal active ingredient for high-performance formulations.

    FAQ - Technical & Supply Chain

    • Q:

      How is Alpha Cypermethrin (CAS 67375-30-8) chemically distinguished from generic Cypermethrin?

      A: Alpha Cypermethrin consists primarily of the two most active cis-isomers of cypermethrin, resulting in significantly higher insecticidal potency and lower required dosage rates compared to the standard cypermethrin mixture which contains all eight isomers.
    • Q:

      Is this technical grade Alpha Cypermethrin intended for direct field application?

      A: No, this technical material is intended for industrial processing and must be formulated into specific delivery systems (such as emulsifiable concentrates or suspension concentrates) before it can be applied in agricultural or public health settings.
