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 chiral diphosphine ligand features two (2R,5R)-2,5-dimethylphospholano groups tethered by a benzene bridge, delivering high stereocontrol in asymmetric catalysis. The sterically shielded phosphorus centers enhance catalyst stability and selectivity in transition-metal-catalyzed transformations.

Application

1,2-Bis[(2R,5R)-2,5-dimethylphospholano]benzene serves as a robust, bench-stable chiral ligand enabling highly selective transition-metal-catalyzed transformations. Its rigid, sterically demanding phospholano framework enhances enantioselectivity in palladium- and nickel-catalyzed cross-couplings, offering improved functional group tolerance and reproducible yields in asymmetric synthesis workflows.
