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

1,2-Dibromo-5-chloro-3-fluorobenzene features a highly halogenated aromatic core with strategically positioned bromine, chlorine, and fluorine substituents. This electron-deficient scaffold enables direct incorporation into cross-coupling reactions, serving as a robust building block for complex heterocycles and functional materials under standard conditions.

Application

1,2-Dibromo-5-chloro-3-fluorobenzene serves as a versatile building block in cross-coupling chemistry, enabling the synthesis of complex substituted arenes under palladium-catalyzed conditions. The strategic placement of bromo, chloro, and fluoro substituents provides orthogonal reactivity for sequential functionalization, while the molecule exhibits excellent bench stability and ease of purification. Its defined electronic profile facilitates predictable coupling outcomes, making it well-suited for medicinal chemistry and materials science applications requiring precise substitution patterns.
