Description

4-Iodo-n-Methylbenzenesulfonamide is a specialized organoiodine compound that serves as a valuable synthetic intermediate in advanced organic chemistry. Its core value lies in the combination of the sulfonamide moiety and the iodine substituent, which provides a versatile handle for further functionalization via cross-coupling reactions. This high-purity building block is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing novel active ingredients and complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel drug candidates, especially those targeting central nervous system (CNS) disorders and other therapeutic areas.
• Agrochemical Research: Used in the development of new pesticides and herbicides, where the iodine atom facilitates the introduction of other functional groups.
• Material Science: Employed in the synthesis of functionalized polymers and advanced materials with specific electronic or photonic properties.
• Cross-Coupling Reactions: Serves as a crucial substrate in palladium-catalyzed reactions, such as Suzuki, Stille, and Sonogashira couplings, for carbon-carbon bond formation.
• Chemical Biology Probes: Utilized in the creation of molecular probes and labeled compounds for biochemical and diagnostic research.
• Ligand Synthesis: Acts as a precursor for synthesizing specialized ligands used in catalysis and coordination chemistry.

Quality Control

Our 4-Iodo-n-Methylbenzenesulfonamide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical R&D and production processes.

Storage

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