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

4-Bromo-3-chloro-5-nitropyridine features a tri-substituted pyridine core with complementary halogen and nitro groups enabling precise functionalization. The electron-deficient ring facilitates cross-coupling reactions, while the ortho-halogen arrangement supports sequential derivatization. This robust scaffold integrates efficiently into complex heterocyclic architectures under standard conditions.

Application

4-Bromo-3-chloro-5-nitropyridine serves as a versatile building block in medicinal chemistry and heterocyclic synthesis, enabling selective cross-coupling reactions via its bromo and chloro substituents. The nitro group provides a handle for sequential reduction and functionalization, while the pyridine core offers predictable reactivity in palladium-catalyzed transformations. Its bench-stable nature and compatibility with diverse reaction conditions facilitate efficient construction of complex scaffolds in API development.
