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

This chiral bis-imidazole features two cyclohexyl and two para-tolyl substituents positioned at the 4 and 4′-vertices, creating a rigid, electron-rich scaffold with enhanced steric shielding. The tetrahydrobiimidazole core provides stability and facilitates coordination in asymmetric catalysis. Its defined stereochemistry at the 4 and 4′ positions enables precise control in transition-metal complexes.

Application

(4S,4'S)-4,4'-Dicyclohexyl-1,1'-di-p-tolyl-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole serves as a sterically hindered, bench-stable chiral ligand that facilitates asymmetric catalysis in transition-metal-mediated transformations. Its rigid biimidazole core with complementary aryl and cyclohexyl substituents enables precise stereocontrol in cross-coupling and hydrogenation reactions, offering high functional group tolerance and ease of purification.
