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

3-Bromo-2,4-difluoropyridine is a fluorinated heterocyclic building block featuring orthogonal reactivity at the bromo and difluoro positions. This electron-deficient pyridine scaffold enables selective cross-coupling and nucleophilic substitution under standard conditions, facilitating efficient access to complex functionalized architectures in medicinal chemistry and materials science.

Application

3-Bromo-2,4-difluoropyridine serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromine at C3 facilitates selective functionalization, while the 2,4-difluoro substitution pattern enhances electrophilicity for nucleophilic aromatic substitution. Its bench stability and compatibility with diverse reaction conditions make it ideal for constructing complex heterocyclic scaffolds in API development.
