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-Bromo-4-iodobenzonitrile features a dual halogen substitution pattern enabling efficient cross-coupling reactions. The nitrile group provides a polar handle for further functionalization, while the bromine and iodine sites offer orthogonal reactivity in palladium-catalyzed transformations. This compound serves as a key intermediate in the synthesis of bioactive heterocycles and advanced pharmaceutical scaffolds.

Application

2-Bromo-4-iodobenzonitrile serves as a versatile biaryl building block in cross-coupling chemistry, enabling efficient access to substituted phenyl nitriles via Pd-catalyzed reactions. The bromo and iodo groups offer orthogonal reactivity for sequential functionalization, while the nitrile moiety provides a handle for downstream transformations. Bench-stable and compatible with standard Suzuki, Stille, and Negishi protocols, it facilitates rapid assembly of complex scaffolds in medicinal chemistry and materials science.
