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

Description

2-Bromo-5-nitro-3-(trifluoromethyl)pyridine features a trifluoromethyl group and a nitro substituent positioned ortho to the bromine, creating a highly electron-deficient pyridine core. This combination enables selective cross-coupling reactions under mild conditions, with enhanced stability compared to analogous halogenated heterocycles. The molecule’s robust reactivity profile supports efficient integration into complex synthetic architectures.

Application

2-Bromo-5-nitro-3-(trifluoromethyl)pyridine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its reactive bromide and electron-deficient pyridine core. The trifluoromethyl and nitro groups provide strong electron-withdrawing effects, enhancing regioselectivity in C–H functionalization and facilitating the construction of complex heterocyclic scaffolds. Its bench stability and compatibility with standard purification methods make it well-suited for multi-step synthesis workflows.
