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

(2S,2'S,3S,3'S)-WingPhos is a sterically tuned, bench-stable phosphine ligand featuring a rigid biaryl backbone with strategically positioned substituents. This configuration enhances stability and electron density while promoting efficient palladium-catalyzed cross-coupling reactions under mild conditions. The ligand excels in challenging C–O and C–N bond formations, offering high selectivity and catalyst longevity in complex molecule synthesis.

Application

(2S,2'S,3S,3'S)-WingPhos serves as a highly effective, bench-stable phosphine ligand in palladium-catalyzed cross-coupling reactions. Its rigid, sterically defined structure enables selective C–C and C–heteroatom bond formation under mild conditions, with excellent functional group tolerance and consistent performance in Suzuki-Miyaura, Negishi, and Stille couplings. Designed for reproducible results in complex molecule synthesis, it facilitates efficient catalyst activation and minimizes decomposition pathways during scale-up.
