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
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

2-Bromo-3,5-dichloropyrazine is a halogenated pyrazine derivative featuring complementary reactive sites for cross-coupling and functionalization. This electron-deficient heterocycle integrates readily into synthetic scaffolds requiring precise substitution patterns. The molecule exhibits enhanced stability under standard bench conditions and serves as a key intermediate in the development of bioactive compounds and advanced materials.

Application

2-Bromo-3,5-dichloropyrazine serves as a versatile heterocyclic building block in medicinal chemistry and agrochemical synthesis. Its orthogonal halogenation pattern enables selective metal-catalyzed cross-coupling reactions, particularly Suzuki-Miyaura and Buchwald-Hartwig transformations, under mild conditions. The molecule exhibits good bench stability and facilitates efficient functionalization of pyrazine scaffolds with high regiocontrol, making it valuable for constructing complex nitrogen-containing frameworks.
