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

This chiral phosphine ligand features a rigid dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin scaffold with two sterically demanding naphthylethyl substituents. The (11bS) stereochemistry and N,N-bis(1-naphthalenylethyl) groups confer exceptional enantioselectivity in palladium-catalyzed cross-coupling reactions. Bench-stable and moisture-tolerant, it integrates seamlessly into asymmetric synthesis workflows.

Application

(11bS)-N,N-Bis[(1S)-1-(1-naphthalenyl)ethyl]dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine serves as a sterically encumbered, bench-stable chiral phosphine ligand that enables efficient transition-metal-catalyzed cross-coupling reactions. Its rigid dinaphtho scaffold and tertiary amine functionality confer excellent functional group tolerance and reproducible catalytic performance in Pd-catalyzed Suzuki-Miyaura and Negishi couplings, facilitating the construction of complex biaryl and heterocyclic architectures with high enantioselectivity.
