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

(S,S)-tBu-Dbfox is a bench-stable, chiral bis(oxazoline) ligand featuring a tert-butyl-substituted dihydroxybenzene core. This sterically hindered architecture enhances enantioselectivity in transition-metal-catalyzed asymmetric reactions, particularly in copper-mediated transformations. The ligand's robustness under standard conditions enables reliable performance in process development workflows.

Application

(S,S)-tBu-Dbfox serves as a highly effective chiral ligand in asymmetric transition metal catalysis, enabling enantioselective transformations such as allylic alkylation and conjugate addition. Its robust tert-butyl substituents enhance steric control and bench stability, while the dibenzofuran scaffold provides rigidity and favorable electronic properties. The ligand demonstrates excellent functional group tolerance and reproducible enantioselectivity in established synthetic protocols, making it a practical choice for scalable asymmetric synthesis.
