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-Bromo-3-chloro-5-fluoropyridine is a halogenated pyridine derivative featuring strategically positioned bromo, chloro, and fluoro substituents. This combination enables selective functionalization in late-stage diversification of pharmaceutical intermediates. The molecule exhibits enhanced reactivity in palladium-catalyzed cross-coupling processes due to orthogonal halogen sensitivity. Its stability under standard bench conditions supports reliable handling in synthetic workflows.

Application

2-Bromo-3-chloro-5-fluoropyridine serves as a versatile trifunctional pyridine building block for cross-coupling and nucleophilic substitution reactions. Its orthogonal halogen reactivity enables sequential functionalization in medicinal chemistry and agrochemical synthesis, with the bromo group typically participating in Pd-catalyzed couplings while chloro and fluoro substituents offer enhanced stability and selective activation under defined conditions.
