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+

Description

(SP-4-1)-[1,3-Bis[2,6-bis(1-propylbutyl)phenyl]-4,5-dichloro-1,3-dihydro-2H-imidazol-2-ylidene]dichloro(3-chloropyridine-κN)-Palladium is a sterically shielded palladium(II) complex featuring two bulky 1-propylbutyl-substituted aryl groups that enhance stability and solubility. The dichloro ligands and κN-bound 3-chloropyridine facilitate reactivity in cross-coupling transformations under mild conditions. This complex integrates readily into catalytic systems requiring robust, electron-deficient Pd centers with enhanced resistance to decomposition.

Application

(SP-4-1)-[1,3-Bis[2,6-bis(1-propylbutyl)phenyl]-4,5-dichloro-1,3-dihydro-2H-imidazol-2-ylidene]dichloro(3-chloropyridine-κN)-Palladium serves as a robust, bench-stable N-heterocyclic carbene palladium complex enabling efficient cross-coupling reactions under mild conditions. Its sterically shielded ligand framework enhances catalyst longevity and tolerates diverse functional groups, facilitating reliable C–C and C–heteroatom bond formation in synthetic and process chemistry workflows.
