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
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

2-Bromo-3-fluoro-4-nitropyridine features a tri-functionalized pyridine core with distinct halogen and nitro groups enabling precise diversification in heterocyclic synthesis. The ortho-bromo and fluoro substituents facilitate palladium-catalyzed cross-coupling, while the electron-deficient nitro group enhances reactivity in nucleophilic substitution. This compound serves as a key intermediate in pharmaceutical and agrochemical development.

Application

2-Bromo-3-fluoro-4-nitropyridine serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The nitro group provides a handle for selective reduction and further functionalization, while the fluorine substituent enhances metabolic stability in downstream pharmaceutical scaffolds. Its bench-stable nature and compatibility with diverse reaction conditions facilitate efficient access to complex pyridine derivatives used in medicinal chemistry and agrochemical development.
