EASTFINE is a specialized manufacturer of 3-Fluoro-4-iodotoluene, a high-purity halogenated aromatic compound (C7H6FI).2 This compound is a crucial synthetic intermediate and building block due to the highly reactive C-I bond and the presence of the fluorine atom, offering a specific meta-fluoro electronic and steric profile. This meta-fluoro-para-iodo substitution pattern makes it uniquely valuable in the synthesis of complex pharmaceuticals, agrochemicals, and advanced materials where precise chemical functionalization is required. Our product is supplied as a colorless to light yellow liquid requiring cold, dark storage.

Product Description
EASTFINE is a leading supplier of 3-Fluoro-4-iodotoluene, a core building block in modern chemical synthesis. The combination of the reactive iodo group and the non-reactive, electronically influential fluoro group, both positioned relative to the methyl group, makes this molecule an essential starting material. Its primary utility lies in forming new carbon-carbon bonds through various cross-coupling reactions (e.g., Suzuki, Sonogashira), enabling chemists to construct complex aromatic scaffolds with the essential meta-fluorine substitution often desired in bioactive molecules.
At EASTFINE, our 452-79-9 intermediate is produced under rigorous quality control to guarantee its purity and optimal reactivity for high-yield synthetic processes.

As a dedicated 452-79-9 manufacturer, EASTFINE ensures a stable and high-quality supply. Our synthetic procedures are optimized to deliver product purity of min. 97%, which is critical for preventing side reactions in sensitive catalytic coupling methodologies. Since the compound is light-sensitive and an organoiodide, our material is meticulously packaged and shipped under controlled, dark conditions, and we strongly recommend cold storage (2-8℃ or below) under an inert atmosphere to maintain product integrity and chemical reactivity over time.

3-Fluoro-4-iodotoluene is highly valued because it provides an excellent substrate for forming new C-C bonds via cross-coupling reactions (like Suzuki, Sonogashira). The C-I bond is highly reactive and readily cleaved under catalytic conditions, while the fluorine atom is a stable, non-leaving group. Its meta position relative to the methyl group and ortho position relative to the iodo group creates a unique electronic and steric environment, making it a powerful tool for introducing the 3-fluorotoluene scaffold, which is a common structural motif in medicinal chemistry.
3-Fluoro-4-iodotoluene is a liquid that can cause skin and eye irritation. Standard personal protective equipment must be used during handling. Due to its C-I bond, it is particularly sensitive to light and oxygen, which can lead to degradation (free iodine formation). To maintain high purity and stability, the manufacturer recommends storage in a cool, dark place (preferably 2-8℃ or in a freezer for long periods), tightly sealed under an inert atmosphere (such as argon or nitrogen).
While both compounds share the exact same molecular formula (C7H6FI) and have the same functional groups, their chemical reactivity differs significantly due to the positional isomerism. In 452-79-9 (3-Fluoro-4-iodotoluene), the fluoro group is meta to the methyl group and ortho to the iodo group. In 443-85-6 (2-Fluoro-6-iodotoluene), both the fluoro and iodo groups are ortho to the methyl group. This difference in position dramatically affects the electronic and steric bulk around the reaction center, making each isomer suitable for different, highly specific synthetic pathways and final product designs.
