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

3-Bromo-2-chloro-5-methylpyrazine is a halogenated pyrazine derivative featuring strategically positioned bromo, chloro, and methyl substituents. This configuration enables selective cross-coupling reactions in synthetic chemistry, particularly in the construction of functionalized heterocycles. The compound exhibits enhanced reactivity due to the electron-withdrawing nature of the halogens, facilitating palladium-catalyzed transformations under mild conditions. Its bench-stable solid form simplifies handling and storage in standard laboratory environments.

Application

3-Bromo-2-chloro-5-methylpyrazine serves as a versatile heterocyclic building block for medicinal chemistry and agrochemical synthesis. Its complementary halogenation pattern enables sequential cross-coupling reactions, including Suzuki-Miyaura and Stille couplings, with high regioselectivity. The methyl group enhances solubility and modulates electronic properties, while the bench-stable crystalline solid facilitates handling and purification.
