Product Overview

1,4-Diiodobenzene 98% is a high-purity aromatic compound widely used in organic synthesis due to its dual iodine substituents, which enhance reactivity in cross-coupling and substitution reactions. This reagent is particularly valued for its stability under standard lab conditions, making it ideal for applications requiring precise halogenation or aryl-aryl bond formation. The 98% purity ensures minimal impurities, reducing the need for additional purification steps in sensitive reactions. Its crystalline or powdered form allows for easy handling and accurate weighing, while the iodine atoms provide a strong leaving group for further functionalization. Whether used in Suzuki-Miyaura couplings, nucleophilic substitutions, or as a precursor for more complex organic molecules, this compound delivers consistent performance. The product is packaged in airtight containers to prevent moisture absorption and degradation, ensuring long-term stability. Researchers and chemists rely on this reagent for its predictable behavior and compatibility with a wide range of solvents and reaction conditions.

FAQs

1. What is the shelf life of 1,4-Diiodobenzene 98% when stored properly?

When stored in a cool, dry place away from direct sunlight and moisture, 1,4-Diiodobenzene 98% maintains its purity and reactivity for up to 24 months from the date of manufacture.

2. Is this compound compatible with common organic solvents like THF or DCM?

Yes, 1,4-Diiodobenzene 98% is soluble in most organic solvents, including tetrahydrofuran (THF), dichloromethane (DCM), and dimethylformamide (DMF), making it versatile for various reaction setups.

3. Can this reagent be used as a substitute for 1,4-dibromobenzene in coupling reactions?

While structurally similar, 1,4-diiodobenzene offers higher reactivity in certain coupling reactions due to the weaker carbon-iodine bond compared to carbon-bromine, but compatibility depends on the specific reaction conditions.

4. What precautions should be taken while handling this chemical?

Handle in a fume hood with proper protective equipment, including gloves and goggles, as iodine compounds can be irritating to skin and mucous membranes. Avoid inhalation of dust or vapors.

5. Does this product require any special storage conditions beyond standard lab practices?

Store in a tightly sealed container under inert gas if long-term storage is needed, as prolonged exposure to air or humidity may lead to gradual degradation or discoloration.
