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
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

3,4-Dibromobenzaldehyde features a dibrominated aromatic ring flanking an aldehyde group, delivering enhanced electrophilicity and stability for cross-coupling reactions. This bench-stable reagent integrates efficiently into synthetic sequences requiring halogenated aryl building blocks, particularly in the construction of complex pharmaceutical intermediates and functional materials.

Application

3,4-Dibromobenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling efficient access to brominated aromatic scaffolds via cross-coupling and electrophilic substitution reactions. Its dual bromine substituents provide orthogonal reactivity for sequential functionalization, while the aldehyde group facilitates condensation, reduction, or heterocycle formation. The compound exhibits good bench stability and is readily purified by crystallization, making it well-suited for use in medicinal chemistry campaigns and process development workflows.
