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-Chloro-3-phenylquinoxaline is a halogenated quinoxaline derivative featuring a chlorine atom at the 2-position and a phenyl group at the 3-position. This electron-deficient heterocycle integrates readily into cross-coupling reactions, serving as a robust scaffold for constructing complex aromatic systems in medicinal chemistry and materials science.

Application

2-Chloro-3-phenylquinoxaline serves as a versatile building block for transition-metal-catalyzed cross-coupling reactions, enabling efficient construction of biaryl and heterobiaryl architectures. Its chlorine substituent facilitates palladium-catalyzed coupling with boronic acids and amines, while the phenyl group enhances stability and solubility. The quinoxaline core provides a rigid, planar scaffold suitable for pharmaceutical and materials applications.
