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-2-chloro-3-fluoropyridine is a halogenated pyridine derivative featuring strategically positioned bromo, chloro, and fluoro substituents. This combination enables selective cross-coupling reactions in pharmaceutical synthesis, offering enhanced reactivity and stability under standard conditions. The molecule’s electron-deficient core facilitates efficient palladium-catalyzed transformations, while its bench-stable nature supports reliable handling in process development workflows.

Application

5-Bromo-2-chloro-3-fluoropyridine serves as a versatile trifunctional pyridine building block for medicinal chemistry and process development. Its orthogonal halogenation pattern enables sequential cross-coupling reactions, including Suzuki, Stille, and Negishi couplings, with high chemoselectivity. The molecule exhibits excellent bench stability and facilitates efficient late-stage functionalization in API synthesis.
