Description

Chrysanthemoyl Chloride is a key reactive intermediate in organic synthesis, primarily used for the production of pyrethroid insecticides. Its high reactivity makes it an essential building block for creating potent and selective active ingredients. This compound is critical for manufacturers in the agrochemical and pharmaceutical industries who require a reliable, high-purity precursor for advanced chemical synthesis.

Application

• Primary Intermediate for Pyrethroid Synthesis: Acts as a crucial precursor in the manufacture of synthetic pyrethroid insecticides such as allethrin, prallethrin, and other chrysanthemate esters.
• Agrochemical Manufacturing: Used in the production of household and agricultural insecticides, providing rapid knockdown effects against a wide range of insects.
• Pharmaceutical Intermediate: Serves as a building block in the synthesis of certain pharmaceutical compounds and active pharmaceutical ingredients (APIs).
• Research & Development: Employed in chemical R&D for developing new insecticidal agents and studying structure-activity relationships.
• Fine Chemical Synthesis: Utilized in specialized organic synthesis where the introduction of the chrysanthemoyl moiety is required.

Quality Control

Our Chrysanthemoyl Chloride is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency, suitable for sensitive synthesis processes. We provide comprehensive Certificates of Analysis (COA) with each batch, detailing key parameters such as assay, isomer content, and impurity profiles. Our quality system is designed to meet the stringent requirements of the agrochemical and fine chemical industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its properties as a strong acid/organic solvent, hygroscopic (moisture-sensitive), and highly volatile nature, it must be kept away from moisture, heat, and incompatible materials such as bases and oxidizing agents. Use appropriate corrosion-resistant storage equipment.
