Description

trans-Chrysanthemic Acid CAS NO 827-90-7 is a key chiral intermediate and a cyclopropane carboxylic acid derivative widely used in the synthesis of pyrethroid insecticides. Its structural configuration is critical for imparting high biological activity and low mammalian toxicity in the final agrochemical products. This compound is essential for manufacturers in the agrochemical and fine chemical industries seeking to produce advanced, effective crop protection agents.

Application

• Primary Intermediate for Pyrethroid Synthesis: Serves as a crucial chiral building block for the production of synthetic pyrethroids like allethrin, tetramethrin, and phenothrin.
• Agrochemical Manufacturing: Used in the formulation of household and agricultural insecticides due to its potent insecticidal activity derived from its specific stereochemistry.
• Fine Chemical Synthesis: Employed in organic synthesis and pharmaceutical research for constructing complex molecules containing the cyclopropane ring, a valuable structural motif.
• Biochemical Research: Utilized in studies of insect neurotoxins and sodium channel modulators to understand mode of action and develop new active ingredients.
