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-Hydroxy-3,5-diiodobenzaldehyde features a hydroxyl group flanked by two iodine atoms on the aromatic ring, delivering enhanced electron-withdrawing character and strategic functional handles. This configuration enables direct incorporation into coupling reactions and facilitates downstream derivatization in synthetic medicinal chemistry. The aldehyde functionality offers high reactivity for imine formation and oxime ligation under mild conditions.

Application

4-Hydroxy-3,5-diiodobenzaldehyde serves as a versatile building block for iodinated aromatic scaffolds in medicinal chemistry and materials science. The aldehyde group enables direct functionalization via nucleophilic addition or condensation reactions, while the ortho-hydroxyl and diiodo substituents provide sites for Suzuki-Miyaura coupling and further derivatization. Bench-stable and compatible with standard purification methods, it facilitates efficient access to complex heterocyclic systems and bioactive intermediates.
