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

(11bR)-2,6-Dimethyl-N,N-bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine is a sterically hindered phosphine ligand featuring a rigid dinaphtho dioxaphosphepin scaffold. This configuration enhances thermal stability and resistance to oxidation while maintaining high reactivity in palladium-catalyzed cross-coupling processes. The bulky chiral aryl substituents promote selectivity in asymmetric transformations.

Application

(11bR)-2,6-Dimethyl-N,N-bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine serves as a sterically hindered, bench-stable phosphine ligand that enables efficient transition-metal-catalyzed cross-coupling reactions. Its rigid dinaphtho scaffold and chiral bis(1-phenylethyl) substituents provide excellent functional group tolerance and enhanced catalyst stability, facilitating reliable coupling in complex molecule synthesis.
