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-5-cyclopropylpyrazine features a cyclopropyl group that enhances lipophilicity and metabolic stability, while the bromine substituent enables facile cross-coupling reactions. This scaffold integrates readily into diverse heterocyclic architectures under standard conditions, offering a robust platform for medicinal chemistry and materials synthesis.

Application

2-Bromo-5-cyclopropylpyrazine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions to construct biaryl and heteroaryl scaffolds. The bromine atom facilitates efficient functionalization under standard Suzuki, Stille, or Negishi conditions, while the cyclopropyl group enhances metabolic stability and modulates lipophilicity. Its bench-stable nature and compatibility with diverse reaction conditions make it ideal for iterative synthesis of complex heterocyclic systems.
