Description

cis-Chrysanthemic Acid is a key chiral intermediate and a fundamental structural component of pyrethroid insecticides. This compound matters for its role as a critical building block in the synthesis of highly effective, low-toxicity pest control agents. Industries that require it include agrochemical manufacturers for producing synthetic pyrethroids, as well as research institutions developing novel insecticidal compounds and fine chemical synthesis.

Application

• Primary Intermediate for Pyrethroid Synthesis: Serves as the core acid moiety for constructing Type I and Type II pyrethroid insecticides like allethrin, tetramethrin, and phenothrin.
• Agrochemical Manufacturing: Essential in the large-scale production of household and agricultural insecticides known for their rapid knockdown effect on insects.
• Fine Chemical Research: Used in academic and industrial R&D to explore new derivatives with improved insecticidal activity or altered biological properties.
• Chiral Pool Synthesis: Provides a valuable, enantiomerically pure starting material for the asymmetric synthesis of complex natural products and bioactive molecules.
• Reference Standard: Employed as an analytical standard in quality control laboratories for the identification and quantification of pyrethroid active ingredients and their metabolites.
