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

(R)-H8-Binap is a chiral bisphosphine ligand featuring a rigid biphenyl backbone with strategically positioned electron-donating groups. This configuration enhances metal coordination stability in asymmetric catalysis, particularly in palladium- and rhodium-catalyzed reactions. The (R)-enantiomer imparts high enantioselectivity, enabling efficient synthesis of chiral intermediates under standard conditions.

Application

(R)-H8-Binap serves as a chiral ligand in transition-metal-catalyzed asymmetric synthesis, enabling high enantioselectivity in reactions such as hydrogenation and cross-coupling. Its rigid biphenyl backbone and sterically defined phosphine groups provide excellent configurational stability and predictable stereocontrol, making it well-suited for bench-scale applications requiring reproducible enantioselectivity.
