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

2,6-Bis(diphenylphosphino)pyridine is a bidentate phosphine ligand featuring two diphenylphosphino groups positioned at the 2 and 6 positions of a pyridine ring. This spatial arrangement enables strong chelation with transition metals, delivering enhanced stability and tunable electronic properties in catalytic systems. The ligand exhibits excellent solubility in organic solvents and maintains integrity under standard handling conditions.

Application

2,6-Bis(diphenylphosphino)pyridine serves as a versatile bidentate phosphine ligand in transition metal catalysis, enabling efficient cross-coupling reactions and homogeneous catalytic transformations. Its rigid pyridine backbone and sterically accessible phosphine donors enhance catalyst stability and reactivity, particularly in palladium- and nickel-catalyzed processes. The ligand exhibits excellent bench stability, facilitates easy purification, and demonstrates broad functional group tolerance in synthetic workflows.
