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-Dibromoterephthalaldehyde features two bromine atoms positioned at the para and meta sites relative to the aldehyde groups, creating a highly functionalized aromatic scaffold. This electron-deficient core enables selective coupling reactions in synthetic organic chemistry, particularly in cross-coupling and cyclization processes. The molecule exhibits enhanced stability under standard bench conditions and integrates readily into complex molecular architectures requiring halogen-directed functionalization.

Application

2,5-Dibromoterephthalaldehyde serves as a versatile dihalogenated aromatic aldehyde building block for the synthesis of functionalized heterocycles and conjugated materials. Its orthogonal reactivity—enabling selective cross-coupling, nucleophilic addition, or oxidative transformations—makes it valuable in medicinal chemistry and materials science applications. Bench-stable and readily purified by recrystallization, it functions effectively in Pd-catalyzed coupling protocols and serves as a key intermediate in the construction of complex aromatic scaffolds.
