Product Description
EASTFINE is a leading supplier of 4-Fluoro-3-iodotoluene, a core building block in modern chemical synthesis. The positioning of the highly reactive iodo group and the electronically influential fluoro group allows for exceptional control over subsequent C-C bond formation. Its primary utility lies in forming new carbon skeletons through various cross-coupling reactions (e.g., Suzuki, Sonogashira), enabling chemists to construct complex aromatic scaffolds with the desired para-fluoro substitution and utilizing the ortho-iodo site for facile reaction.
At EASTFINE, our 452-82-4 intermediate is produced under rigorous quality control to guarantee its purity and optimal reactivity for high-yield synthetic processes.

As a dedicated 452-82-4 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℃) under an inert atmosphere to maintain product integrity and chemical reactivity over time
4-Fluoro-3-iodotoluene provides a unique advantage by combining the highly reactive ortho-iodo group (relative to the methyl group) with the electronically significant para-fluoro group. The ortho-iodo position is ideal for C-C bond formation via cross-coupling reactions (like Suzuki) due to reduced steric hindrance compared to the 2-iodo isomer, yet it is still highly activated. The para-fluoro substitution ensures the final coupled product carries the valuable 4-fluorotoluene motif, known to enhance the biological activity and metabolic stability of drug and agrochemical candidates.
4-Fluoro-3-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 (forming free iodine). To maintain high purity and stability, the manufacturer recommends storage in a cool, dark place (preferably 2-8℃), tightly sealed under an inert atmosphere (such as argon or nitrogen).
While both isomers share the C7H6FI formula, their substitution patterns differ subtly: in 452-82-4 (4-Fluoro-3-iodotoluene), the iodo group is in the 3-position (ortho to methyl, meta to fluoro), while in 13194-67-7 (4-Fluoro-2-iodotoluene), the iodo group is in the 2-position (ortho to methyl, meta to fluoro). This difference changes the steric environment around the C-I bond, which slightly modifies the kinetics and selectivity in C-C cross-coupling reactions, allowing chemists to choose the optimal isomer for specific synthetic requirements.
