Description

2,3-Dichloromaleylacetate CAS NO 146764-41-2 is a specialized chlorinated maleylacetate derivative, a high-value intermediate in advanced organic synthesis. Its unique structure, featuring two chlorine atoms on the maleate core, makes it a critical building block for constructing complex molecules with specific electronic and steric properties. This compound is essential for research and development chemists and manufacturers in the agrochemical and pharmaceutical sectors, where it is used to create novel active ingredients and functional materials.

Application

• Agrochemical Intermediate: A key precursor in the synthesis of novel herbicides, fungicides, and plant growth regulators, leveraging its reactive dichloro-substituted structure.
• Pharmaceutical Building Block: Used in the research and development of active pharmaceutical ingredients (APIs), particularly for constructing complex heterocycles and receptor-targeting molecules.
• Specialty Chemical Synthesis: Serves as a versatile intermediate for producing dyes, pigments, and functional polymers that require specific chlorinated motifs.
• Material Science Research: Employed in developing advanced organic electronic materials and metal-organic frameworks (MOFs) due to its potential as a functional linker or monomer.
• Cross-Coupling Reactions: Acts as a substrate in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) to create complex, conjugated systems.

Quality Control

Our 2,3-Dichloromaleylacetate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets precise customer specifications and high-purity standards for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flames. Due to the potential sensitivity of chlorinated organic compounds, it is recommended to store under an inert atmosphere for long-term stability and to minimize moisture uptake.
