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-2,5-difluorobenzene features a highly functionalized aromatic core with bromine and fluorine substituents positioned for orthogonal reactivity. This electron-deficient scaffold enables selective cross-coupling transformations under palladium catalysis, offering access to complex fluorinated biaryls. The molecule exhibits enhanced stability and compatibility with standard reaction conditions.

Application

1,3-Dibromo-2,5-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, while the dibromo functionality offers sequential functionalization potential. Bench-stable and compatible with standard reaction conditions, it facilitates efficient construction of fluorinated aromatic scaffolds relevant to medicinal chemistry and materials science.
