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

This piperidine-substituted dioxaphosphepin features a sterically hindered, bench-stable phosphorus center with enhanced reactivity in cross-coupling transformations. The fused dinaphtho architecture imparts rigidity and electronic tuning, enabling efficient incorporation into catalytic systems for C–P bond formation under mild conditions.

Application

1-((11bR)-2,6-dimethyldinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-yl)piperidine serves as a sterically encumbered, bench-stable phosphine ligand that facilitates palladium-catalyzed cross-coupling reactions. Its rigid dioxaphosphepin core enhances thermal stability and electron density at phosphorus, enabling efficient Suzuki-Miyaura and Negishi couplings with diverse aryl and heteroaryl halides. The piperidine moiety provides solubility and functional group tolerance, supporting scalable synthesis of complex biaryls and pharmaceutical intermediates.
