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-Dibromo-1,3-difluorobenzene features a symmetrically substituted aromatic core with bromine and fluorine atoms at strategic positions, enabling selective cross-coupling reactions. The electron-withdrawing fluorine groups enhance reactivity in palladium-catalyzed transformations, while the dibromo configuration supports sequential functionalization. This compound serves as a key building block for advanced materials and pharmaceutical intermediates, offering predictable regiochemistry and stability under standard conditions.

Application

2,5-Dibromo-1,3-difluorobenzene serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions due to its complementary halogen reactivity. The difluoro substitution pattern enhances metabolic stability and modulates electronic properties, making it valuable for constructing fluorinated aromatic scaffolds in medicinal chemistry. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient synthesis of complex targets.
