    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.

Description

(SP-4-1)-[1,3-Bis[2,6-bis(1-methylethyl)phenyl]-1,3-dihydro-2H-imidazol-2-ylidene]dichloro(1-methyl-1H-imidazole-κN3)palladium is a sterically shielded palladium(II) complex featuring a bulky N-heterocyclic carbene ligand. The electron-rich carbene moiety enhances stability and facilitates oxidative addition under standard conditions. This robust catalyst enables efficient cross-coupling reactions in demanding synthetic transformations.

Application

(SP-4-1)-[1,3-Bis[2,6-bis(1-methylethyl)phenyl]-1,3-dihydro-2H-imidazol-2-ylidene]dichloro(1-methyl-1H-imidazole-κN3)palladium serves as a robust, bench-stable precatalyst for palladium-catalyzed cross-coupling reactions. Its sterically encumbered N-heterocyclic carbene ligand enhances catalyst longevity and tolerates diverse functional groups, enabling efficient C–C and C–heteroatom bond formation under standard reaction conditions. Ideal for Suzuki-Miyaura, Negishi, and Stille couplings, it facilitates high yields with minimal metal leaching, supporting scalable synthesis and streamlined purification workflows.
