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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

(R,R)-BaryPhos is a chiral diphosphine ligand featuring a rigid, electron-rich backbone that enhances enantioselectivity in palladium-catalyzed cross-coupling reactions. Its sterically defined architecture enables high stereoselectivity and catalyst stability under standard conditions, delivering consistent performance in asymmetric synthesis workflows.

Application

(R,R)-BaryPhos serves as a highly effective chiral diphosphine ligand in palladium-catalyzed cross-coupling reactions, enabling efficient C–C bond formation with excellent enantioselectivity. Its robust bench stability and broad functional group tolerance facilitate reliable performance in asymmetric Suzuki-Miyaura and Negishi couplings, making it a practical choice for the synthesis of enantiomerically enriched biaryl and alkenyl scaffolds in medicinal chemistry and process development.
