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

Description

This sterically encumbered phosphine features a rigid, electron-rich dioxaphosphepin core that enhances stability and reactivity in palladium-catalyzed cross-coupling processes. The (11bS) stereochemistry ensures predictable coordination geometry, while the phenoxy substituent improves solubility and resistance to oxidation under standard conditions.

Application

(11bS)-4-Phenoxy-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin serves as a stereochemically defined phosphorus heterocycle with established utility in asymmetric synthesis. The phenoxy substituent enhances solubility and stability, while the rigid dioxaphosphepin core facilitates controlled reactivity in transition-metal-catalyzed transformations. It functions as a versatile building block for phosphorus-containing scaffolds, enabling efficient access to chiral ligands and catalysts through well-documented functional group interconversions.
