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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00

Description

2,5-Dibromo-4-fluoropyridine features a fluorinated pyridine core with bromine substituents at the 2 and 5 positions, enabling efficient cross-coupling transformations. The electron-deficient aromatic ring pairs well with palladium catalysts, while the ortho-bromine atoms provide regioselective functionalization pathways. This compound serves as a key building block in medicinal chemistry and materials synthesis, offering high reactivity under standard conditions.

Application

2,5-Dibromo-4-fluoropyridine serves as a versatile building block for the synthesis of functionalized pyridine derivatives, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The fluorine and bromine substituents provide complementary sites for sequential functionalization, facilitating access to complex heterocyclic scaffolds. Its bench-stable nature and compatibility with standard coupling conditions make it well-suited for medicinal chemistry and process development workflows.
