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

3-Bromo-4-iodophenol features a phenolic hydroxyl group flanked by bromo and iodo substituents at adjacent positions, enabling selective functionalization in cross-coupling reactions. The electron-withdrawing halogens enhance reactivity while maintaining stability under standard conditions, facilitating incorporation into complex molecular architectures.

Application

3-Bromo-4-iodophenol serves as a versatile diaryl building block for palladium-catalyzed cross-coupling reactions, enabling efficient construction of biaryl scaffolds. Its orthogonal halogen reactivity—bromine readily participates in Suzuki, Stille, and Negishi couplings while iodine supports rapid Buchwald-Hartwig amination—facilitates sequential functionalization. The phenolic hydroxyl group offers additional handle for derivatization or protection, enhancing synthetic flexibility. Bench-stable and amenable to purification by recrystallization, it functions reliably in iterative synthesis workflows.
