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

This bidentate phosphine ligand features two diphenylphosphino groups positioned ortho to the biphenyl linkage, enabling robust coordination to transition metals. Its rigid, electron-rich architecture enhances catalytic activity in palladium- and nickel-catalyzed cross-coupling reactions, offering improved stability and selectivity under standard conditions.

Application

2,2'-Bis(diphenylphosphino)-1,1'-biphenyl serves as a versatile, bench-stable ligand in transition metal catalysis, enabling efficient cross-coupling reactions and palladium-catalyzed transformations. Its rigid biphenyl backbone and orthogonal phosphine groups provide strong metal coordination, enhancing catalyst activity and selectivity in Suzuki-Miyaura, Stille, and Negishi couplings. Ideal for complex molecule synthesis, it offers excellent functional group tolerance and ease of purification in industrial and academic settings.
