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-(4-Bromo-1H-pyrazol-1-yl)pyrazine features a brominated pyrazole moiety fused to a pyrazine core, enabling efficient coupling in cross-coupling reactions. The electron-deficient pyrazine ring enhances reactivity in transition-metal-catalyzed transformations, while the bromine atom serves as a reliable handle for further functionalization. This compound exhibits bench-stable handling and compatibility with standard synthetic protocols.

Application

2-(4-Bromo-1H-pyrazol-1-yl)pyrazine serves as a versatile building block for constructing bioactive heterocyclic scaffolds. The bromo group enables palladium-catalyzed cross-coupling reactions, facilitating the assembly of complex molecules under mild conditions. Its pyrazine core provides enhanced solubility and metabolic stability, while the 1H-pyrazole moiety offers orthogonal reactivity for further functionalization. This compound exhibits excellent bench stability and is compatible with standard purification protocols, making it ideal for medicinal chemistry and process development workflows.
