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

1,3-Dibromo-2,4-difluorobenzene features two bromine atoms at meta positions relative to each other and flanking a pair of fluorine substituents, creating a highly electron-deficient aromatic core. This structural arrangement enables selective cross-coupling reactions in late-stage functionalization, particularly under palladium catalysis. The molecule exhibits enhanced stability under standard bench conditions and tolerates a range of reaction environments, making it suitable for use in complex synthetic sequences requiring precise regiocontrol.

Application

1,3-Dibromo-2,4-difluorobenzene serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The difluoro substitution enhances metabolic stability and modulates electronic properties, making it valuable for constructing bioactive heterocycles and pharmaceutical scaffolds. Its bench-stable nature and compatibility with standard purification methods support reliable use in iterative synthesis workflows.
