Description

Ethyl Chrysanthemumate is a synthetic ester derivative of chrysanthemic acid, a key structural motif found in natural pyrethrins. This compound serves as a crucial intermediate and building block in the synthesis of advanced pyrethroid insecticides and other fine chemicals. It is essential for manufacturers in the agrochemical, pharmaceutical, and specialty chemical industries seeking to develop potent and targeted active ingredients.

Application

• Agrochemical Intermediate: Primary use as a key synthon in the production of synthetic pyrethroid insecticides (e.g., allethrin, tetramethrin derivatives).
• Fine Chemical Synthesis: Serves as a chiral building block for pharmaceutical research and the development of novel bioactive molecules.
• Flavor & Fragrance Industry: Used in the synthesis of certain aroma chemicals, contributing to complex floral and green notes.
• Research & Development: Critical reference standard and starting material in academic and industrial R&D for pest control agents.
• Specialty Additives: Potential application in the formulation of performance chemicals and functional additives.
