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 diphenylphosphine derivative features a 2',6'-dimethoxybiphenyl scaffold that enhances electron density and steric bulk at the phosphorus center. The ortho-methoxy groups improve solubility and stability while facilitating efficient coupling in palladium-catalyzed cross-coupling reactions.

Application

(2',6'-Dimethoxy[1,1'-biphenyl]-2-yl)diphenylphosphine serves as a robust, bench-stable ligand in palladium-catalyzed cross-coupling reactions. Its electron-rich dimethoxy-substituted biphenyl framework enhances catalyst activity and stability, enabling efficient coupling of aryl halides and boron reagents under mild conditions. The ligand exhibits excellent functional group tolerance and facilitates clean reaction profiles with straightforward purification, making it well-suited for scalable synthesis of complex biaryl architectures.
