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-Bromo-1,4-dichlorobenzene is a halogenated aromatic compound featuring complementary reactive sites for cross-coupling and functionalization. The bromo group enables palladium-catalyzed coupling reactions, while the para-dichloro substitution provides structural rigidity and enhanced stability. This scaffold serves as a key intermediate in synthesizing complex polycyclic architectures and bioactive molecules.

Application

2-Bromo-1,4-dichlorobenzene serves as a versatile building block in cross-coupling chemistry, enabling palladium-catalyzed reactions such as Suzuki-Miyaura and Stille couplings due to its stable halogen functionality. The ortho-bromine facilitates selective transformation while the para-dichloro substitution provides electronic tuning and enhanced bench stability. Its predictable reactivity and ease of purification make it a practical choice for constructing complex aryl scaffolds in medicinal chemistry and materials science applications.
