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-5-iodo-1H-benzo[d]imidazole features a fused bicyclic core with orthogonal halogen substituents enabling selective cross-coupling. The electron-deficient imidazole ring facilitates palladium-catalyzed reactions, while the chlorine and iodine positions allow sequential functionalization. This scaffold delivers high reactivity under standard coupling conditions, offering efficient access to complex heterocyclic architectures in medicinal chemistry and materials science applications.

Application

2-Chloro-5-iodo-1H-benzo[d]imidazole serves as a versatile building block for heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The chloro and iodo substituents allow sequential functionalization, with the iodo group exhibiting high reactivity in Suzuki, Stille, and Negishi couplings. Bench-stable and readily purified by recrystallization, it functions effectively in constructing biologically relevant imidazole scaffolds under standard reaction conditions.
