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

2,2′-Binaphthalene features a rigid, chiral backbone with orthogonal naphthalene units, enabling precise spatial control in asymmetric synthesis. This scaffold integrates readily into ligands and catalysts, offering enhanced stereoinduction in transition-metal-catalyzed reactions under standard conditions.

Application

2,2′-Binaphthalene serves as a rigid, chiral scaffold enabling asymmetric synthesis through well-established functionalization at the 6,6′-positions. Its planar chirality and bench stability facilitate use in catalytic systems and ligand design, with documented utility in transition-metal-catalyzed transformations and stereoselective heterocycle construction.
