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

(R,R)-BisPh-propabBox features a rigid, chiral bisphosphine scaffold that delivers high enantioselectivity in asymmetric catalysis. The propyl-bridged binaphthyl backbone provides exceptional stability and tunable steric bulk, enabling efficient metal coordination. This ligand excels in palladium- and nickel-catalyzed cross-coupling reactions under mild conditions.

Application

(R,R)-BisPh-propabBox serves as a robust chiral ligand in transition-metal-catalyzed asymmetric synthesis, particularly effective in palladium- and copper-mediated cross-coupling reactions. Its rigid bisphosphine architecture provides strong metal coordination and high enantioselectivity in C–C and C–heteroatom bond formations. The propyl bridge enhances solubility and stability, facilitating bench-scale operations and purification. This ligand enables efficient access to enantiomerically enriched building blocks for pharmaceutical and agrochemical applications.
