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

Description

3,5-Di(2-pyridyl)pyrazole features a rigid, electron-deficient pyrazole core flanked by two 2-pyridyl groups, enabling strong metal coordination. This design delivers high selectivity for transition metals in catalytic systems and supramolecular assemblies. The molecule exhibits excellent bench stability and solubility in common organic solvents, simplifying handling in synthetic workflows.

Application

3,5-Di(2-pyridyl)pyrazole serves as a versatile bidentate ligand in transition metal catalysis, enabling efficient coordination to palladium, copper, and nickel centers. Its rigid, electron-rich architecture enhances complex stability and catalytic turnover in cross-coupling reactions. The molecule exhibits excellent bench stability, facilitates straightforward purification, and demonstrates broad functional group tolerance in standard synthetic workflows.
