3-Iodotoluene (CAS 625-95-6) stands as a fundamental organic compound with significant utility in the chemical industry, particularly as a versatile building block for synthesis. For researchers and product formulation chemists, a deep understanding of its properties and applications is key to unlocking its full potential.

Chemically identified as 1-iodo-3-methylbenzene, 3-Iodotoluene is an aromatic compound belonging to the iodotoluene family. Its molecular structure, C7H7I, features an iodine atom meta-substituted on a toluene ring. This specific arrangement imparts unique reactivity, making it a valuable intermediate in various chemical transformations. In its pure form, it is typically a liquid with a characteristic odor, possessing a boiling point around 80-82°C at 10 mmHg and a density of 1.698 g/cm³.

The applications of 3-Iodotoluene are diverse, primarily revolving around its role as a precursor in organic synthesis. It is frequently employed in the creation of pharmaceutical intermediates, where the iodo-aryl moiety can be readily functionalized through reactions such as Suzuki coupling, Heck reaction, or nucleophilic aromatic substitution. These reactions allow for the introduction of complex carbon chains or other functional groups, leading to the development of novel drug candidates.

Beyond pharmaceuticals, 3-Iodotoluene finds use in the agrochemical sector for synthesizing active ingredients in pesticides and herbicides. Its incorporation into molecules can enhance their efficacy or alter their physical properties for better delivery and targeted action. Furthermore, it serves as a general building block in the synthesis of fine chemicals, dyes, and specialized materials where an iodinated aromatic ring is required.

For chemists looking to purchase 3-Iodotoluene, specifying the required purity is essential. While standard grades might be 96% or 97% pure, higher purities are available for more sensitive applications. Understanding the source—whether it's from a direct manufacturer or a distributor—and requesting a Certificate of Analysis (COA) are crucial steps. Reliable suppliers, often based in regions like China, can offer competitive pricing for bulk quantities, making it economically viable for large-scale production.

When conducting chemical synthesis, formulators should be aware of 3-Iodotoluene's properties, such as its light sensitivity and incompatibility with strong oxidizing agents. Proper storage conditions, typically in a cool, dry place away from direct light, are recommended to maintain its integrity. By leveraging the reactivity and availability of 3-Iodotoluene, chemists can efficiently develop new products and processes across a wide spectrum of chemical industries.
