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+

Description

2-Bromo-3-nitrobenzaldehyde features a bromine atom ortho to a nitro group on a benzaldehyde scaffold, creating a highly electron-deficient aromatic ring. This combination enables efficient coupling in cross-coupling reactions and facilitates regioselective functionalization. The aldehyde group provides a handle for further derivatization, including reductive amination or condensation chemistry. Bench-stable under standard conditions, it serves as a key building block in synthetic medicinal chemistry and materials science.

Application

2-Bromo-3-nitrobenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling the construction of substituted heterocycles and functionalized aromatic systems. Its dual electrophilic sites—bromine and aldehyde—facilitate palladium-catalyzed cross-couplings and nucleophilic additions, while the nitro group enhances reactivity in reduction and cyclization sequences. Bench-stable and readily purified by recrystallization, it supports scalable synthesis workflows in medicinal chemistry and materials development.
