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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

1,3-Bis(4-chlorophenyl)-1H-imidazol-3-ium chloride features a rigid, electron-deficient imidazolium core flanked by two 4-chlorophenyl groups, enhancing its stability and solubility in polar solvents. This charged scaffold serves as a robust building block for ionic liquids and catalytic systems requiring strong cationic character and steric protection.

Application

1,3-Bis(4-chlorophenyl)-1H-imidazol-3-ium chloride serves as a stable, bench-ready imidazolium salt widely employed in transition-metal-catalyzed cross-coupling reactions. Its ortho-chloroaryl substituents enable facile functionalization and serve as versatile handles for downstream derivatization. The salt exhibits excellent solubility in polar aprotic solvents, facilitates catalyst activation in Pd-catalyzed processes, and demonstrates robust stability under standard laboratory conditions, making it a reliable building block for synthesizing complex heterocyclic scaffolds and functionalized aryl systems.
