HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

2,4-Dimethoxyiodobenzene is a bench-stable aryl iodide featuring two electron-donating methoxy groups that enhance reactivity in cross-coupling transformations. The para-substituted methoxy moiety stabilizes the iodine center while improving solubility in polar organic solvents. This derivative enables efficient Pd-catalyzed coupling reactions under mild conditions, offering predictable regiochemistry and high functional group tolerance for complex molecule assembly.

Application

2,4-Dimethoxyiodobenzene serves as a stable, bench-ready aryl iodide building block for palladium-catalyzed cross-coupling reactions. The ortho-dimethoxy substitution enhances solubility and functional group tolerance while enabling predictable regioselective transformations. Its stability under ambient conditions facilitates handling and purification, making it ideal for constructing complex heterocycles and pharmaceutical scaffolds via Suzuki-Miyaura, Stille, or Negishi coupling protocols.
