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-fluoro-4-(methylsulfonyl)benzene features a trifunctional aryl scaffold combining bromine, fluorine, and a robust methylsulfonyl group. This configuration enables direct incorporation into cross-coupling reactions, offering high stability under standard conditions. The electron-withdrawing methylsulfonyl moiety enhances reactivity in palladium-catalyzed transformations while maintaining excellent bench stability and moisture tolerance.

Application

1-Bromo-2-fluoro-4-(methylsulfonyl)benzene serves as a versatile building block in cross-coupling chemistry, enabling efficient palladium-catalyzed transformations due to its orthogonal halogen reactivity. The bromo group facilitates coupling with boronic acids, while the fluorine and methylsulfonyl substituents provide enhanced stability and directed functionalization potential. This compound exhibits excellent bench stability and is well-suited for the synthesis of substituted biaryls and heterocyclic scaffolds in medicinal chemistry and materials science applications.
