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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

4,5-Dibromo-1,2-dimethyl-1H-imidazole features two bromine atoms at the 4 and 5 positions of the imidazole ring, flanked by methyl groups at the 1 and 2 positions. This electron-deficient heterocycle serves as a stable, bench-accessible building block for transition metal-catalyzed cross-coupling reactions. The sterically protected core enables selective functionalization in complex molecule synthesis.

Application

4,5-Dibromo-1,2-dimethyl-1H-imidazole serves as a versatile building block for the synthesis of brominated heterocyclic scaffolds. Its dual bromine substituents enable efficient cross-coupling reactions, while the methyl groups provide steric and electronic modulation. The compound exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for iterative functionalization in medicinal chemistry and materials science applications.
