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+

Description

This chiral bis-imidazole features two (S)-sec-butyl groups and sterically shielded tert-butylphenyl substituents, delivering enhanced stability and solubility in organic media. The rigid, C₂-symmetric scaffold enables precise spatial control in asymmetric catalysis and molecular recognition applications.

Application

(4S,4'S)-4,4'-Di((S)-sec-butyl)-1,1'-bis(3-(tert-butyl)phenyl)-4,4',5,5'-tetrahydro-1H,1'H-2,2'-biimidazole serves as a sterically encumbered, chiral bis-imidazole ligand designed for transition-metal catalysis. Its robust bench stability and orthogonal functional group tolerance enable reliable coordination in Pd- or Ni-catalyzed cross-coupling reactions. The (S)-sec-butyl and tert-butyl substituents provide enhanced stereochemical control and prevent undesired aggregation, facilitating efficient catalyst turnover and purification in asymmetric synthesis workflows.
