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

(S,S)-QuinoxP is a chiral bis-oxazoline ligand featuring two quinoxaline-derived heterocycles, designed for asymmetric transition-metal catalysis. This rigid, electron-rich scaffold enables high enantioselectivity in copper- and zinc-mediated reactions, particularly in C–C bond formation. The (S,S) configuration ensures optimal stereocontrol in catalytic cycles, offering robust performance under standard bench conditions with minimal decomposition.

Application

(S,S)-QuinoxP serves as a robust chiral ligand in asymmetric catalysis, enabling high enantioselectivity in palladium- and nickel-catalyzed cross-coupling reactions. Its rigid quinoxaline backbone and sterically defined (S,S)-configured phosphine groups provide excellent functional group tolerance and bench stability, facilitating efficient synthesis of enantiopure biaryl and heteroaryl scaffolds commonly found in pharmaceutical intermediates.
