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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

3,3',5,5'-Tetramethyl-1H,1'H-4,4'-bipyrazole features a rigid, electron-rich bipyrazole core with methyl groups at the 3 and 5 positions on each ring, enhancing steric protection and solubility. This configuration promotes stability under standard conditions while enabling reliable coordination in metal-ligand frameworks. The molecule integrates readily into functional architectures requiring robust, planar binding sites.

Application

3,3',5,5'-Tetramethyl-1H,1'H-4,4'-bipyrazole serves as a robust, bench-stable bipyrazole scaffold for ligand design and heterocyclic synthesis. Its methyl-substituted pyrazole rings enhance solubility and stability while enabling efficient coordination to transition metals in catalytic systems. The molecule facilitates modular assembly of functionalized heterocycles and functions effectively in Pd-catalyzed cross-coupling reactions due to its defined electronic profile and resistance to decomposition under standard reaction conditions.
