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-2-iodopyridine is a heteroaryl halide featuring distinct bromo and iodo substituents at adjacent positions on the pyridine ring. This configuration enables selective cross-coupling reactions, particularly in palladium-catalyzed transformations, where the differing reactivities of the halogens facilitate sequential functionalization. The molecule exhibits excellent stability under standard conditions, enabling reliable use in complex synthetic sequences.

Application

4-Bromo-2-iodopyridine serves as a versatile dihalogenated pyridine building block for cross-coupling reactions, enabling efficient access to substituted heterocycles. Its orthogonal halogen reactivity facilitates sequential Pd-catalyzed couplings, with the bromo group typically undergoing reaction first. The compound exhibits good bench stability and is compatible with standard reaction conditions, simplifying purification and integration into complex molecular architectures.
