Description

4,6-Dichloroisophthaloyl Dichloride is a high-purity, reactive aromatic diacid chloride derivative. This compound serves as a critical building block in advanced organic synthesis, enabling the formation of high-performance polymers and complex molecular architectures. It is essential for R&D and production in the pharmaceutical, agrochemical, and specialty polymer industries, where its dual acyl chloride functionality facilitates the creation of amide and ester linkages under controlled conditions.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring isophthalic acid-derived scaffolds.
• Polymer Chemistry: Monomer for the production of high-performance polyamides, polyimides, and polyester resins with enhanced thermal and chemical resistance.
• Agrochemical Synthesis: Used in creating advanced herbicide and pesticide molecules that benefit from its chlorinated aromatic structure.
• Liquid Crystal Polymers (LCPs): Building block for aromatic monomers used in engineering thermoplastics and liquid crystal polymer production.
• Dye and Pigment Manufacturing: Intermediate in the synthesis of complex organic dyes and pigments, contributing to color fastness and stability.
• Cross-linking Agent: Functions as a reactive cross-linker in coatings, adhesives, and composite materials to improve mechanical properties.
• Laboratory Reagent: Used in academic and industrial research for method development and the synthesis of novel organic compounds.
• Material Science: Precursor for metal-organic frameworks (MOFs) and other advanced porous materials with tailored properties.

Quality Control

Our 4,6-Dichloroisophthaloyl Dichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from moisture, bases, and oxidizing agents.
