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

1-Bromo-2-chloro-3,5-difluorobenzene is a halogenated aromatic compound featuring complementary reactive sites for cross-coupling transformations. The ortho-bromo and chloro substituents enable sequential functionalization, while the electron-deficient fluorine atoms enhance regioselectivity in palladium-catalyzed reactions. This bench-stable reagent integrates efficiently into complex molecular architectures under standard conditions.

Application

1-Bromo-2-chloro-3,5-difluorobenzene serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions such as Suzuki-Miyaura and Buchwald-Hartwig arylations. Its orthogonal halogen reactivity profile—bromine for coupling, chlorine and fluorines for stability—facilitates selective functionalization. The compound exhibits excellent bench stability, ease of purification, and compatibility with diverse reaction conditions, making it ideal for constructing complex heterocyclic scaffolds and drug-like molecules.
