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

Description

3-Bromo-5-iodobenzaldehyde features a dual-halogenated aromatic core with distinct reactivity at both bromine and iodine sites. The aldehyde group enables direct functionalization in cross-coupling and conjugation workflows. This electron-deficient scaffold integrates readily into complex molecular architectures under standard conditions, offering predictable regioselectivity in palladium-catalyzed transformations.

Application

3-Bromo-5-iodobenzaldehyde serves as a versatile bifunctional building block for cross-coupling cascades and sequential functionalization in medicinal chemistry. The aldehyde group enables direct derivatization via imine formation or reductive amination, while the bromo and iodo substituents support palladium-catalyzed coupling reactions with broad scope. Its bench-stable crystalline form facilitates handling and purification, making it ideal for constructing complex heterocyclic scaffolds and targeted API intermediates.
