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-difluorobenzene features a strategically positioned bromine and two fluorine substituents on the benzene ring, enabling selective coupling reactions in pharmaceutical synthesis. This electron-deficient aryl halide exhibits enhanced stability under standard conditions and facilitates efficient cross-coupling transformations.

Application

2-Bromo-1,4-difluorobenzene serves as a versatile building block in cross-coupling chemistry, enabling the synthesis of substituted aromatic systems through Pd-catalyzed reactions. The ortho-bromine and para-fluorine substituents provide orthogonal reactivity for sequential functionalization, facilitating the construction of complex heterocycles and pharmaceutical scaffolds. Bench-stable and compatible with standard reaction conditions, it offers reliable performance in iterative synthetic sequences.
