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

2,3-Dibromo-1,4-difluorobenzene features a rigid aromatic core bearing two bromine atoms at adjacent positions and two fluorine substituents at the para relationship, enabling selective cross-coupling reactions. The electron-withdrawing fluorine groups enhance reactivity in palladium-catalyzed transformations while maintaining stability under standard handling conditions. This dual halogenation pattern facilitates sequential functionalization in synthetic sequences requiring precise regiocontrol.

Application

2,3-Dibromo-1,4-difluorobenzene serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromine atoms facilitate Suzuki, Stille, and Negishi couplings, while the fluorine substituents enhance metabolic stability and modulate electronic properties in target molecules. Its bench-stable nature and compatibility with diverse reaction conditions make it a practical choice for constructing complex aromatic scaffolds in medicinal chemistry and materials science applications.
