NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer High Purity Isophthalic Acid (PIA), a critical chemical intermediate known for its exceptional quality and versatility. As a leading supplier in the chemical industry, NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing raw materials that meet the stringent demands of various industrial applications. Isophthalic Acid, with the CAS number 121-91-5, is a white crystalline powder that serves as a fundamental building block in the synthesis of numerous high-performance materials.

Our High Purity Isophthalic Acid boasts a minimum purity of ≥99.9%, ensuring consistent performance and reliability in downstream processes. This high level of purity is achieved through meticulous manufacturing processes and rigorous quality control measures. Key specifications underscore its premium quality: an Acid Number ranging from 673 to 677 mgKOH/g, moisture content strictly limited to ≤0.1%, Ash content at ≤15 ppm, Total metal content ≤10.00 ppm, and specific trace metals like Fe, Co, and Mn kept below ≤1.00 ppm each. These specifications are vital indicators of its suitability for sensitive applications where impurities can compromise final product integrity and performance.

The physical properties of Isophthalic Acid further enhance its utility. It is characterized as an inflammable substance with low toxicity, exhibiting the property of sublimation. While it is only slightly soluble in water, its solubility in organic solvents such as ethanol and glacial acetic acid makes it amenable to various reaction and formulation processes. Its insolubility in benzene is another distinguishing feature. These properties dictate its handling requirements and influence its behavior during chemical reactions, making it a preferred choice for specific synthesis pathways.

One of the primary applications of Isophthalic Acid is in the production of unsaturated polyester resins. The incorporation of PIA into these resins imparts enhanced chemical resistance, thermal stability, and mechanical strength. This makes PIA-based polyester resins ideal for demanding applications in fiberglass composites used in boat hulls, automotive parts, construction materials, and pipes. The structural integrity and durability provided by Isophthalic Acid contribute significantly to the longevity and performance of these composite materials under harsh environmental conditions.

Beyond unsaturated polyester resins, Isophthalic Acid is also extensively used in the synthesis of alkyd resins. Alkyd resins are widely employed in the coatings industry, particularly for high-quality paints and enamels. PIA improves the hardness, gloss retention, and weather resistance of these coatings, resulting in finishes that are both aesthetically pleasing and exceptionally durable. The chemical structure contributed by Isophthalic Acid enhances crosslinking density, leading to tougher and more resilient film formations on various substrates.

Furthermore, Isophthalic Acid finds application in the production of plasticizers, other specialized polymers, and as a component in film couplers. In the textile industry, it can be used as a dyeing agent for polyester fibers, influencing dye uptake and colorfastness properties. Its role in pharmaceutical modification highlights its importance as a versatile chemical intermediate that can be used to synthesize or modify compounds with potential therapeutic properties, though PIA itself is a raw material, not a finished drug product.
