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

7-Bromo-4-fluorobenzofuran is a heterocyclic building block featuring complementary halogen substituents that enable selective cross-coupling reactions. The electron-deficient aromatic core, flanked by bromo and fluoro groups at distinct positions, facilitates palladium-catalyzed transformations with high regiocontrol. This scaffold exhibits excellent stability under standard conditions and integrates readily into complex molecular architectures for medicinal chemistry and materials science applications.

Application

7-Bromo-4-fluorobenzofuran serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its complementary halogen reactivity. The bromo and fluoro substituents offer orthogonal functionalization potential, facilitating sequential derivatization. Bench-stable and readily purified by flash chromatography, it functions effectively in Suzuki, Stille, and Negishi couplings for constructing complex heterocyclic scaffolds and API intermediates.
