EASTFINE is a specialized manufacturer
of 3-Iodophthalic acid, a high-purity iodinated aromatic dicarboxylic acid used extensively as a functionalized building block in organic synthesis. Featuring both an iodine atom and two adjacent carboxylic acid groups on a benzene ring, it is particularly valuable for synthesizing complex C-I bond derivatives and in coordination chemistry research, such as the study of metal ion interactions (e.g., with uranyl ion). Our product is supplied as a stable, high-ppurity solid suitable for academic and industrial research applications.

As a dedicated 6937-34-4 3-Iodophthalic acid manufacturer, EASTFINE guarantees a stable supply of this key building block. Our manufacturing process, often involving the Sandmeyer-type reaction of 3-Aminophthalic acid, is optimized to deliver product purity of min.98%. Every batch is subject to rigorous analytical testing to confirm structure and purity. We ensure secure packaging and compliant logistics to maintain the quality of this solid chemical, which should be stored in dry, dark conditions at ambient temperature.
3-Iodophthalic acid serves as a vital intermediate in synthesizing complex organic molecules, particularly those requiring a combination of aromatic dicarboxylic acid and halogen functionality. The C-I bond is highly reactive and can be easily utilized in cross-coupling reactions (like Suzuki or Sonogashira couplings) to introduce complex carbon frameworks. Additionally, the dicarboxylic acid groups are excellent chelating ligands, making the compound useful in studies involving coordination chemistry and metal-organic frameworks, such as the documented research on its interaction with the uranyl ion.
The high-purity 3-Iodophthalic acid supplied by EASTFINE is a stable solid that should be stored in a dark place, sealed in dry conditions, and kept at room temperature. Although it is not temperature-sensitive like some liquids, prolonged exposure to light and moisture may lead to degradation or decomposition, affecting its high purity and performance in sensitive chemical reactions. It is also an irritant, requiring appropriate handling with personal protective equipment.
The phthalic acid core (benzene-1,2-dicarboxylic acid) is a fundamental structure. Introducing the large, heavy, and moderately electron-withdrawing iodo substituent at the 3-position significantly modifies the molecule's properties. It alters the pKa of the carboxylic acid groups, affects its solubility, and, most importantly, provides a highly versatile reactive site (the C-I bond) for orthogonal functionalization in complex synthetic routes. This combination of a reactive halogen and strong metal-binding sites is what makes 3-Iodophthalic acid a valuable specialty chemical.
