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

7-Bromo-2-chloro-1H-benzo[d]imidazole features a fused heterocyclic core with complementary halogen substituents enabling precise functionalization. The bromine and chlorine atoms facilitate palladium-catalyzed cross-coupling reactions, while the electron-deficient imidazole ring enhances reactivity in C–H activation and transition-metal-mediated transformations. This scaffold serves as a robust building block for bioactive molecules and advanced materials.

Application

7-Bromo-2-chloro-1H-benzo[d]imidazole serves as a versatile heterocyclic building block in medicinal chemistry and materials science. Its dual halogenation pattern enables palladium-catalyzed cross-coupling reactions, including Suzuki-Miyaura and Buchwald-Hartwig aminations, with high functional group tolerance. The molecule exhibits excellent bench stability and facilitates efficient purification, making it well-suited for modular synthesis of biologically active scaffolds and advanced organic semiconductors.
