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+

Description

This sterically encumbered phosphine oxide features two biphenyl moieties flanking a hydroxylated dioxaphosphepin core, delivering exceptional thermal and oxidative stability. The 11bR stereochemistry ensures predictable reactivity in asymmetric synthesis, enabling efficient coupling under mild conditions.

Application

(11bR)-2,6-Bis([1,1'-biphenyl]-4-yl)-4-hydroxy-4-oxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin serves as a robust, bench-stable phosphine oxide scaffold enabling stereoselective transformations in catalytic systems. Its rigid, polycyclic architecture provides excellent functional group tolerance and facilitates efficient P–O bond cleavage under mild conditions, making it valuable for the synthesis of chiral phosphine ligands and transition-metal-catalyzed coupling reactions.
