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 dioxaphosphepin features a chiral 11bR configuration and a hydroxylated, electron-deficient phosphorus center. The ortho-methylated aryl substituents confer exceptional stability and solubility in nonpolar media, enabling robust performance in asymmetric catalysis and transition-metal-free phosphorylation reactions under ambient conditions.

Application

(11bR)-4-Hydroxy-2,6-bis(2,4,6-trimethylphenyl)-4-oxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin serves as a sterically encumbered, bench-stable phosphine oxide with enhanced oxidative stability. It functions as a robust ligand in palladium-catalyzed cross-coupling reactions, enabling efficient C–C bond formation under mild conditions. Its ortho-substituted aryl groups confer high functional group tolerance and facilitate easy purification, making it well-suited for iterative synthesis in medicinal chemistry and process development workflows.
