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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

(2R,2'R,3R,3'R)-WingPhos is a sterically hindered, electron-rich phosphine ligand designed for palladium-catalyzed cross-coupling reactions. Its chiral backbone enhances enantioselectivity in asymmetric transformations, while the bulky substituents promote catalyst stability and facilitate rapid reductive elimination. This ligand enables efficient coupling under mild conditions with broad functional group tolerance.

Application

(2R,2'R,3R,3'R)-WingPhos is a highly effective chiral bisphosphine ligand that enables asymmetric hydrogenation and cross-coupling reactions with excellent enantioselectivity. Its rigid, electron-rich structure enhances catalyst stability and turnover, facilitating robust performance in transition-metal-catalyzed transformations. This ligand serves as a reliable tool for synthesizing chiral intermediates in pharmaceutical and agrochemical applications, offering superior selectivity and operational simplicity in standard laboratory workflows.
