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-chloropyrazine is a heteroaromatic dihalogenated pyrazine featuring complementary reactivity at distinct ring positions. This electron-deficient scaffold enables selective cross-coupling transformations under palladium catalysis, facilitating the construction of complex nitrogen-containing architectures in medicinal chemistry and materials science.

Application

2-Bromo-5-chloropyrazine serves as a versatile heterocyclic building block for transition-metal-catalyzed cross-coupling reactions, enabling the efficient construction of biaryl and functionalized pyrazine scaffolds. Its complementary halogenation pattern offers orthogonal reactivity in palladium- or nickel-catalyzed coupling processes, facilitating rapid diversification in medicinal chemistry and materials science applications. The compound exhibits good bench stability and is compatible with standard purification protocols.
