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+

Description

t-BuXphos Palladacycle Gen. 4 delivers a sterically hindered, bench-stable palladium complex engineered for efficient cross-coupling under mild conditions. Featuring a robust xanthene-based ligand framework, it enables rapid activation and stable catalytic turnover in Suzuki-Miyaura and Negishi reactions. This catalyst excels in challenging substrates with poor reactivity, offering high functional group tolerance and minimal Pd leaching.

Application

t-BuXphos Palladacycle Gen. 4 serves as a highly effective precatalyst in palladium-catalyzed cross-coupling reactions, enabling efficient C–C and C–heteroatom bond formation under mild conditions. Its robust steric and electronic profile enhances catalyst longevity and turnover, particularly in challenging substrates. The ligand’s bench-stable nature and compatibility with diverse functional groups make it ideal for scalable synthesis and complex molecule assembly.
