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

Description

4-Bromo-2-chloro-5-fluoropyridine is a halogenated pyridine derivative featuring strategically positioned bromo, chloro, and fluoro substituents. This electron-deficient heterocycle enables direct coupling in cross-coupling reactions, serving as a key building block for pharmaceutical intermediates and functional materials. The combination of halogens allows sequential functionalization under palladium catalysis, facilitating access to complex molecular architectures with high regiocontrol.

Application

4-Bromo-2-chloro-5-fluoropyridine serves as a versatile heterocyclic building block for medicinal chemistry and materials science. Its orthogonal halogenation pattern enables sequential cross-coupling reactions, including Pd-catalyzed Suzuki, Stille, and Negishi couplings. The molecule exhibits excellent bench stability and facilitates efficient functionalization under standard reaction conditions, making it ideal for constructing complex pyridine-based scaffolds in API development and advanced organic synthesis.
