Description

(E)-trans-(+)-Chrysanthemumdicarboxylic Acid CAS NO 33383-55-0 is a high-purity, stereochemically defined intermediate of significant importance in the synthesis of advanced pyrethroid insecticides. This compound matters because it provides the critical cis-chrysanthemic acid backbone, enabling the production of more potent and environmentally targeted pest control agents. It is primarily needed by manufacturers in the agrochemical industry for developing next-generation crop protection products, as well as by research institutions focused on fine chemical synthesis and insecticide mode-of-action studies.

Application

• Key Intermediate for Pyrethroid Synthesis: Serves as a crucial precursor in the manufacturing of synthetic pyrethroid insecticides such as allethrin, phenothrin, and tetramethrin.
• Agrochemical Research & Development: Used in R&D laboratories for the discovery and development of novel insecticidal compounds with improved efficacy and selectivity.
• Fine Chemical Production: Employed in the multi-step synthesis of complex, stereospecific molecules for specialized chemical applications.
• Reference Standard: Utilized as an analytical standard in quality control laboratories to verify the purity and identity of pyrethroid-based products.

Quality Control

Our (E)-trans-(+)-Chrysanthemumdicarboxylic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification and impurity profiling, to ensure it meets the high standards required for synthetic intermediates. A comprehensive Certificate of Analysis (COA) detailing identity, assay, enantiomeric excess, and related substances is provided with every shipment to guarantee traceability and consistency for your processes.

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 hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture, which can affect product stability and handling properties.
