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.

Type	HazMat Fee
Excepted Quantity	$0.00

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

1-Bromo-4-fluoro-2-iodobenzene features a trihalogenated aromatic core with complementary reactivity for palladium-catalyzed cross-coupling. The strategic placement of bromo, fluoro, and iodo substituents enables sequential functionalization under mild conditions. This ortho-iodo-substituted scaffold offers high regioselectivity in Buchwald-Hartwig amination and Suzuki-Miyaura coupling reactions. The electron-deficient ring enhances coupling efficiency while maintaining stability during storage and handling.

Application

1-Bromo-4-fluoro-2-iodobenzene serves as a versatile trihalogenated benzene building block for palladium-catalyzed cross-coupling reactions. Its orthogonal halogen reactivity enables sequential functionalization, with bromo and iodo groups participating in Suzuki, Stille, or Negishi couplings while the fluoro substituent remains inert under standard conditions. The compound exhibits good bench stability and facilitates efficient access to complex substituted arenes and heterocyclic scaffolds in medicinal chemistry and materials synthesis.
