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

2-Bromo-5-nitropyrazine is a heterocyclic building block featuring a bromo group at the 2-position and a nitro group at the 5-position on the pyrazine ring. This electron-deficient scaffold enables direct functionalization via palladium-catalyzed cross-coupling, offering streamlined access to complex nitrogen-rich architectures in medicinal chemistry and materials science.

Application

2-Bromo-5-nitropyrazine serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its well-established bromine reactivity. The nitro group provides a handle for selective reduction and further functionalization, while the pyrazine core offers inherent stability and electron-deficient character suitable for medicinal chemistry applications. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient incorporation into complex molecular architectures.
