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 electron-rich phosphino groups flanked by sterically shielded 3,5-dimethylphenyl rings, enabling robust coordination to transition metals. The binaphthyl backbone imparts axial chirality and enhances stability in catalytic systems. Ideal for asymmetric synthesis under standard conditions.

Application

2,2'-Bis[di(3,5-dimethylphenyl)phosphino]-1,1'-binaphthyl serves as a highly effective chiral ligand in transition metal-catalyzed asymmetric synthesis. Its sterically shielded phosphine groups enable robust coordination to palladium and ruthenium, facilitating enantioselective C–C and C–heteroatom bond formations. The binaphthyl backbone provides rigidity and high enantiomeric control, while the 3,5-dimethylphenyl substituents enhance solubility and stability under reaction conditions. Ideal for catalytic applications requiring high turnover and reproducible stereocontrol.
