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

2,5-Diiodoterephthalaldehyde features two iodine atoms positioned at the 2 and 5 ring sites of terephthalaldehyde, creating a highly functionalized aromatic scaffold. This electron-deficient di-aldehyde integrates readily into cross-coupling processes, enabling efficient access to complex molecular architectures in medicinal chemistry and materials synthesis. The dual iodide handles provide orthogonal reactivity for sequential transformations.

Application

2,5-Diiodoterephthalaldehyde serves as a versatile building block in synthetic organic chemistry, enabling the construction of complex heterocyclic scaffolds and functionalized aromatic systems. Its two iodine substituents facilitate efficient cross-coupling reactions, while the aldehyde group supports reductive amination, condensation, and protection strategies. The compound exhibits excellent bench stability and is compatible with standard purification methods, making it a practical choice for iterative synthesis workflows in medicinal chemistry and materials science.
