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

5-Bromo-4-chloro-2-fluoropyridine is a halogenated pyridine derivative featuring strategically positioned bromo, chloro, and fluoro substituents. This electron-deficient heterocycle enables direct functionalization in cross-coupling reactions and serves as a key intermediate in medicinal chemistry. The molecule exhibits enhanced reactivity due to orthogonal halogen patterns, facilitating selective transformations under mild conditions.

Application

5-Bromo-4-chloro-2-fluoropyridine serves as a versatile trifunctional pyridine building block, enabling sequential cross-coupling reactions in medicinal chemistry and materials science. Its orthogonal halogen reactivity facilitates palladium-catalyzed transformations—bromine typically reacts first, followed by chlorine and fluorine—allowing precise diversification of complex heterocyclic scaffolds with high regiocontrol and excellent functional group tolerance.
