Description

Potassium 4-Iodo-2-Sulfonato-Benzoic Acid is a high-purity, organoiodine compound that serves as a versatile building block and intermediate in advanced chemical synthesis. Its unique structure, featuring both a sulfonate and a carboxylic acid group as potassium salts, provides excellent water solubility and reactivity for targeted modifications. This product is essential for researchers and manufacturers in the pharmaceutical and specialty chemical industries developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring iodine incorporation for bioactivity or as a radiolabeling handle.
• Ligand and Catalyst Synthesis: Used to prepare specialized ligands for transition metal catalysis, leveraging the sulfonato and carboxylate groups for metal coordination.
• Organic Synthesis Building Block: Employed in cross-coupling reactions (e.g., Suzuki, Sonogashira) where the iodine atom serves as an excellent leaving group for carbon-carbon bond formation.
• Dye and Pigment Manufacturing: Intermediate in the production of iodinated dyes and colorants, where the iodine atom can influence color and lightfastness properties.
• Material Science Research: Component in the development of ionic polymers or metal-organic frameworks (MOFs) due to its anionic, multi-functional character.
• Analytical Chemistry: Potential use as a standard or reagent in analytical methods development and validation.

Quality Control

Every batch of Potassium 4-Iodo-2-Sulfonato-Benzoic Acid is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and commercial synthesis. A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting identity, purity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect purity and stability.
