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

4,4'-Dibromo-2,2'-diiodo-1,1'-biphenyl features two bromine atoms at the 4,4' positions and two iodine atoms at the 2,2' positions on a biphenyl scaffold. This highly halogenated structure enables robust coupling reactions in cross-coupling protocols, particularly under palladium catalysis. The strategic placement of both electron-withdrawing halogens enhances reactivity while maintaining stability under standard conditions.

Application

4,4'-Dibromo-2,2'-diiodo-1,1'-biphenyl serves as a versatile multi-halogenated building block for palladium-catalyzed cross-coupling reactions. Its orthogonal halogen reactivity enables sequential functionalization in complex molecule assembly, particularly in the synthesis of biaryl scaffolds and advanced heterocyclic systems. The compound exhibits excellent bench stability and facilitates efficient purification, making it well-suited for iterative coupling strategies in medicinal chemistry and materials science applications.
