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

This chiral phosphine amine features a rigid dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin scaffold with two naphthalenyl-ethyl substituents in defined stereochemistry. Designed for asymmetric catalysis, it delivers high enantioselectivity in transition metal-mediated transformations. The sterically tuned pocket and electron-rich phosphorus center enable precise substrate control under standard conditions.

Application

(11bS)-N,N-Bis[(1R)-1-(1-naphthalenyl)ethyl]dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine serves as a sterically encumbered, chiral phosphine ligand that enables high-yielding transition-metal-catalyzed cross-coupling reactions. Its rigid dinaphtho scaffold provides excellent thermal stability and robust functional group tolerance, facilitating efficient palladium-catalyzed Suzuki and Negishi couplings under mild conditions. The ligand’s defined stereochemistry enhances enantioselectivity in asymmetric transformations, making it particularly valuable for the synthesis of complex pharmaceutical intermediates and functionalized biaryl architectures.
