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-iodopyrazine is a heteroaromatic dihalogenated pyrazine derivative featuring complementary reactivity at distinct ring positions. This bifunctional scaffold enables efficient cross-coupling transformations in synthetic organic chemistry, particularly in the construction of complex pharmaceutical intermediates and functional materials. The molecule's electron-deficient core supports robust palladium-catalyzed coupling processes under standard conditions.

Application

2-Bromo-5-iodopyrazine serves as a versatile dihalogenated pyrazine building block for cross-coupling reactions, enabling efficient access to substituted heterocycles. Its complementary halogen reactivity profile facilitates sequential Pd-catalyzed coupling processes, with the bromo group typically reacting first under standard conditions. The compound exhibits good bench stability and is readily purified by column chromatography, making it well-suited for synthetic workflows in medicinal chemistry and materials science.
