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.

Description

1,6-Bis(diphenylphosphino)hexane is a bidentate phosphine ligand featuring a flexible hexamethylene backbone that enables optimal coordination geometry in transition metal complexes. The diphenylphosphino groups deliver strong electron donation and steric bulk, enhancing catalyst stability and selectivity in cross-coupling reactions. This ligand exhibits excellent solubility in common organic solvents and maintains integrity under standard handling conditions.

Application

1,6-Bis(diphenylphosphino)hexane serves as a versatile bidentate ligand in transition metal catalysis, particularly in palladium- and nickel-catalyzed cross-coupling reactions. Its rigid yet flexible backbone enables efficient chelation, enhancing catalyst stability and turnover. The ligand demonstrates excellent functional group tolerance and is valued for its bench stability and ease of handling in synthetic workflows requiring selective C–C bond formation.
