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

3-Bromo-5-fluoropyridine is a halogenated pyridine derivative featuring complementary reactive sites for cross-coupling and functionalization. The bromo group enables palladium-catalyzed coupling, while the fluorine at the para position enhances electrophilicity and directs regioselective substitution. This dual functionality supports efficient synthesis of complex heterocycles in medicinal chemistry and materials science.

Application

3-Bromo-5-fluoropyridine serves as a versatile building block in medicinal chemistry and materials science, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromine site undergoes efficient Suzuki, Stille, or Negishi coupling, while the fluorine substituent enhances metabolic stability and modulates electronic properties. Its bench-stable nature and compatibility with diverse reaction conditions make it a practical choice for constructing complex heterocyclic scaffolds and functionalized aryl derivatives in multi-step syntheses.
