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-4-chloro-2,3-difluorobenzene features a highly functionalized aromatic core with orthogonal halogen handles enabling selective cross-coupling. The strategic placement of bromine, chlorine, and two fluorine atoms supports sequential derivatization in complex molecule synthesis. This electron-deficient scaffold delivers enhanced reactivity in palladium-catalyzed transformations while maintaining stability under standard handling conditions.

Application

1-Bromo-4-chloro-2,3-difluorobenzene serves as a versatile building block in cross-coupling chemistry, enabling efficient construction of complex aryl scaffolds. Its orthogonal halogen reactivity profile facilitates sequential functionalization via Pd-catalyzed coupling processes. The molecule exhibits excellent bench stability and compatibility with standard reaction conditions, making it well-suited for medicinal chemistry campaigns and process development.
