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

4,5-Bis(diphenylphosphoroso)-9,9-dimethyl-9h-xanthene is a sterically hindered xanthene-based ligand featuring two diphenylphosphoroso groups that deliver high electron density and enhanced stability in transition metal catalysis. This ligand integrates effectively into palladium- and nickel-catalyzed cross-coupling reactions, enabling efficient bond formation under mild conditions with improved catalyst longevity.

Application

4,5-Bis(diphenylphosphoroso)-9,9-dimethyl-9H-xanthene serves as a highly effective bidentate phosphine ligand in transition metal-catalyzed cross-coupling reactions. Its sterically hindered xanthene backbone enhances stability and electron-donating capacity, enabling efficient palladium- and nickel-catalyzed transformations. The ligand demonstrates robust performance in Suzuki-Miyaura and Negishi couplings, offering improved reaction yields and catalyst turnover under mild conditions. Its bench-stable nature and ease of purification make it well-suited for routine synthetic applications in medicinal chemistry and process development.
