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 sterically hindered 2'-methyl-[1,1'-biphenyl] group that enhances its stability and electron-donating character. It serves as a robust ligand in palladium-catalyzed cross-coupling reactions, offering improved performance under standard conditions.

Application

(2'-Methyl-[1,1'-biphenyl]-2-yl)diphenylphosphine serves as a sterically hindered, electron-rich phosphine ligand that facilitates palladium-catalyzed cross-coupling reactions. Its modular biphenyl backbone provides enhanced stability and tunable steric bulk, enabling efficient coupling in Suzuki-Miyaura and Negishi transformations. The methyl substituent at the 2′-position improves oxidative stability and simplifies purification, making it well-suited for scalable synthesis and process chemistry applications.
