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

1,1,2,2-Tetraphenylethene is a sterically hindered stilbene derivative featuring four phenyl rings attached to the ethene backbone. This configuration imparts exceptional stability and rigidity, enabling its use in photoreactive systems and as a structural scaffold in materials chemistry. The compound exhibits pronounced fluorescence and serves as a key building block in the development of advanced organic semiconductors and molecular switches.

Application

1,1,2,2-Tetraphenylethene serves as a robust, bench-stable building block for conjugated π-systems and heterocyclic synthesis. Its rigid, planar structure facilitates efficient Diels-Alder reactions and enables the construction of complex polycyclic frameworks under mild conditions. The molecule exhibits excellent functional group tolerance and simplifies purification due to its low solubility in common organic solvents, making it ideal for scalable synthetic workflows.
