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.

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

5-Bromo-3-methoxypyrazin-2-amine features a pyrazine core functionalized with bromo and methoxy groups at electron-deficient positions, enabling direct coupling in cross-coupling reactions. The amine handle facilitates derivatization, while the bromine serves as a reactive site for palladium-catalyzed transformations. This compound delivers high reactivity under standard conditions and exhibits bench-stable handling characteristics.

Application

5-Bromo-3-methoxypyrazin-2-amine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its well-defined bromine handle. The methoxy and amino groups provide orthogonal reactivity, facilitating sequential functionalization. Its stability under standard reaction conditions and ease of purification make it suitable for scalable synthesis of pyrazine-based pharmaceutical intermediates and heterocyclic scaffolds.
