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

2,4-Dibromo-5-fluoropyridine is a halogenated pyridine derivative featuring strategic bromo and fluoro substituents that enable selective cross-coupling reactions. The electron-deficient ring facilitates palladium-catalyzed transformations, while the orthogonal halogens allow sequential functionalization. This compound serves as a key intermediate in the synthesis of bioactive heterocycles and advanced pharmaceutical scaffolds.

Application

2,4-Dibromo-5-fluoropyridine serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromine atoms at C2 and C4 facilitate Suzuki, Stille, and Negishi couplings, while the fluorine at C5 enhances electrophilicity for nucleophilic substitution. Its bench-stable crystalline form simplifies handling and purification, making it ideal for constructing complex pharmaceutical scaffolds and functionalized pyridine derivatives in medicinal chemistry workflows.
