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-Bromo-1-chloro-2-iodobenzene features a trihalogenated aromatic core with distinct halogen positions enabling selective cross-coupling reactions. The ortho-iodo and para-bromo substituents facilitate efficient Pd-catalyzed transformations, while the meta-chloro group enhances stability under reaction conditions. This compound serves as a key intermediate in the synthesis of functionalized biaryls and heterocycles.

Application

4-Bromo-1-chloro-2-iodobenzene serves as a versatile trihalogenated benzene building block for palladium-catalyzed cross-coupling reactions. Its orthogonal halogen reactivity enables sequential functionalization, with the iodine moiety typically reacting first under mild conditions. The molecule exhibits excellent bench stability and facilitates efficient diversification in medicinal chemistry and materials synthesis workflows.
