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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

6-Bromo-4-fluoro-1-isopropyl-2-methyl-1H-benzo[d]imidazole features a sterically hindered imidazole core with complementary halogen and alkyl substituents, enabling selective coupling in late-stage functionalization. The electron-deficient aryl ring facilitates palladium-catalyzed cross-coupling reactions under standard conditions, while the isopropyl and methyl groups enhance solubility and stability during synthesis.

Application

6-Bromo-4-fluoro-1-isopropyl-2-methyl-1H-benzo[d]imidazole serves as a versatile building block for the synthesis of bioactive heterocycles, enabling palladium-catalyzed cross-coupling reactions due to its bromine and fluorine substituents. Its isopropyl and methyl groups enhance steric and electronic modulation, facilitating selective functionalization in medicinal chemistry applications. The compound exhibits bench stability and compatibility with standard purification protocols, making it well-suited for scalable synthesis workflows.
