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-methylquinoxaline serves as a key heterocyclic scaffold for constructing advanced pharmaceutical intermediates and functional materials. This electron-deficient quinoxaline derivative features a chloro group at the 2-position and a methyl substituent at the 3-position, enabling selective coupling reactions. The fused ring system imparts stability and facilitates π-stacking interactions in solid-state applications.

Application

2-Chloro-3-methylquinoxaline serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its well-established halogen reactivity. The methyl group provides regiochemical control, while the quinoxaline core offers inherent stability and π-conjugation beneficial for scaffold diversification. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient synthesis of functionalized heterocycles.
