    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

2-Bromoquinoxaline is a bench-stable, electron-deficient heterocycle featuring a bromine atom at the 2-position, enabling direct functionalization in cross-coupling reactions. This configuration enhances reactivity in palladium-catalyzed transformations while maintaining compatibility with diverse reaction conditions. The fused bicyclic core provides structural rigidity and polarity suitable for applications in medicinal chemistry and materials science.

Application

2-Bromoquinoxaline serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions such as Suzuki-Miyaura and Stille couplings. Its bromine substituent facilitates efficient functionalization at the C2 position, while the quinoxaline core provides robust stability and planarity advantageous for constructing heterocyclic scaffolds. The compound exhibits excellent bench stability and compatibility with a wide range of reaction conditions, making it well-suited for medicinal chemistry and materials science applications.
