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

2,3-Dichloro-6,7-dimethylquinoxaline is a sterically hindered, electron-deficient heterocycle featuring two chlorine substituents at the 2,3-positions and methyl groups at the 6,7-positions. This configuration enhances its stability and reactivity in transition metal-catalyzed cross-coupling reactions. The molecule serves as a robust scaffold for constructing complex polycyclic architectures in medicinal chemistry and materials science.

Application

2,3-Dichloro-6,7-dimethylquinoxaline serves as a versatile building block in heterocyclic synthesis, enabling efficient construction of substituted quinoxaline scaffolds via palladium-catalyzed cross-coupling reactions. Its dichloro substitution pattern facilitates sequential functionalization, while the methyl groups enhance solubility and stability under standard reaction conditions. This compound is particularly valuable for medicinal chemistry applications requiring modular access to fused bicyclic systems.
